Algorithm That Diagnoses Heart Arrhythmias

Cardiac arrhythmia is in most cases harmless extras without the disease. Both a slowing of the heart rate (bradycardia) and a speeding up of the heart rate (tachycardia) can also become life threatening. Nearly every person is affected by cardiac arrhythmia during his life.

These can be harmless or dangerous. Often they are only subjectively unpleasant ("stumbling-heart") and do not need treatment. However, untreated pre-fibrillation is accompanied by a marked increase in stroke risk. This makes it all the more important to have an early and reliable algorithm diagnosis. However, they can also lead to dangerous incidents and subsequent episodes.

But how can pre-fibrillation be detected when it occurs irregularly and the patient himself often does not notice it? An ECG - that is, the measurement of cardiac currents - is the gold standard in the algorithm diagnosis of atrial fibrillation. In that case, it can help measure cardiac currents over a longer period of time and keep the heart in view all the time. It is important that even small signals and short episodes can be perceived.

Definition and types of cardiac arrhythmia

The normal heart rate is 50 to 100 beats per minute. The heart rate is generally higher in young women than in men, presumably because in men the rest frequency decreases by frequent sports. A heart rate <50 a="" bradycardia="" called="" frequency="" is="" min="" slowed=""> 100 / min at rest is too fast (tachycardia). Both manifestations of cardiac arrhythmia can be life-threatening. They then usually occur as a result of severe structural heart disease, e.g. Heart attack, cardiac insufficiency, or heart valve defect, or in the case of congenital or severe hypertension caused by hypertension.

Cardiac arrhythmia can be divided into disturbances of stimulation and disorders of the excitatory conduction. Causes of ectopic stimulus formation can be increased automatization, abnormal automatism, and triggered activity. Excitation line disturbances can lead to arrhythmias in linear closed conduction pathways or also in the spatial whole cellular network.

Thanks to the computer scientists at Stanford, who developed an algorithm that diagnoses 14 types of Heart defects. These group of Stanford scientists led by Andrew Ng has developed this deep learning algorithm. With the collaboration with the iRhythm – the heartbeat monitoring company, roll up a solid data set that they used to teach a profound neural network model.

The new heart monitor has now been developed for this purpose. The special feature of this heart monitor, which can also be used on an outpatient basis, is its intelligent design. Its not only records the ECG, it also analyzes it and sends the most important episodes on the so-called home monitoring - a technology built into the implant - to the treating physician every day.

Thanks to this close-meshed observation of the cardiac rhythm, can be detected reliably. This is not only crucial for a safe diagnosis at the beginning of the therapy for cardiac arrhythmia- it may also be necessary to keep a close eye on the heart during treatment.

For example an ablation, that is, an intervention for the obliteration of the diseased cardiac muscle tissue, the doctor sees thanks to home monitoring, whether the procedure was successful or if again atrial fibrillation occurs. The physician can control the therapy better, and the patient gains safety.

Researchers Find New Source of Dangerous Electrical Instability in the Heart

Worldwide, at least 30 million people are living with slogans. In spite of improved treatment options, patients with pre-fibrillation still suffer from stroke, develop heart failure, and die prematurely. On the initiative of the Competence Network, and the European Heart Rhythm Association (EHRA), an international expert group has now developed a plan to improve the quality of the treatment of pre-slurries. The AFNET / EHRA consensus report is published today in the journal EP Europace.

 More than 70 experts from almost every continent participated in the conference and exchanged their experiences. "In view of the great diversity of health systems worldwide, the different countries can learn from each other and develop better models for the treatment of atrial fibrillation. We hope that this plan, which has been created by specialists from different parts of the world, will help to improve the treatment of squibs in Europe and the world, "said Prof. Gerhard Hindricks, President of EHRA.

Several million people in the world have unidentified and therefore untreated pre-fibrillation, combined with a high risk of stroke and death. The AFNET / EHRA Roadmap recommends the introduction of a large-scale pre-screening screening for over-65s and high-risk populations to enable early diagnosis and treatment of pre-fibrillation.

Anticoagulants (anticoagulant drugs for stroke prevention) can only be effective if taken regularly. Therefore, strategies must be defined to minimize disruption or discontinuation of anticoagulation therapy.

Enlightened patients

For a successful therapy of atrial fibrillation - the experts agree on this - all patients should be involved in the decisions about their treatment. The prerequisite for this is that the patients are well informed. In order to achieve this, the authors recommend to improve the availability of free information on pre-ventilations and associated complications and treatment options.

 Patient-friendly initiatives, such as the EHRA-developed patient website, available in five European languages, are considered to be very helpful to the inclusion of the Patients. In addition, "patient reported outcomes" should be used to capture symptoms and consequences of pre-fibrillation from the patient's perspective.

Structured treatment

Adequate treatment of pre-fibrillated patients is complex. Prof. Andreas Gotte, member of the board, said: "Such a aid of pre-fibrillation should check that all patients are offered information based therapy." Therefore, the AFNET / EHRA Plan recommends a structured approach guided by interdisciplinary teams Of care plans for all vaccine patients. Improved therapy

Several million people in the world have unidentified and therefore untreated pre-fibrillation, combined with a high risk of stroke and death. The AFNET / EHRA Roadmap recommends the introduction of a large-scale pre-screening screening for over-65s and high-risk populations to enable early diagnosis and treatment of pre-fibrillation. Anticoagulants (anticoagulant drugs for stroke prevention) can only be effective if taken regularly. Therefore, strategies must be defined to minimize disruption or discontinuation of anticoagulation therapy.

The experts recommend the development of standards with which the quality and success of the pre-flax ablation can be measured uniformly. Frequently, the rhythm disturbance is not completely eliminated by an ablation. Further studies are needed to find the best treatment for patients with presumptive relapse after ablation.

Personalized treatment

Further research is needed to better understand the cellular and molecular mechanisms underlying the pre-fibrillation. The experts propose to evaluate genetic factors, specific biomarkers, and ECG parameters to identify different subtypes of atrial fibrillation in individual patients and to develop more targeted therapies.

For example, new biomarkers or ECG information could be used to better estimate the individual risk of anticoagulation in patients with a medium or low risk of stroke. At present, it is not yet known whether these patients benefit from anticoagulation therapy or not. Prof. A. John Camm, the future president of the EHRA and co-organizers of the Fifth AFNET / EHRA Conference, concludes: "We believe that the proposed research activities can aid to hone the treatment of atrial fibrillation and the treatment for many patients around the world to improve. There is an imperative need for long-term research funding to enable the implementation of sufficiently large studies

Vitamin D 'Heals Damaged Hearts'


Vitamin D Supplement helps Diseased Heart

A study suggests that Vitamin D supplement could help people suffering from diseased heart. A test on 163 patients with heart failure found supplements of the vitamin, made in the skin when it is exposed to sunlight tends to improve the ability of their hearts to pump blood around the body.

A team from Leeds Teaching Hospitals who had presented a meeting of the American College of Cardiology had described the results as `stunning’. The British Heart Foundation had called for longer trials to assess the pills. Vitamin D is considered to be vital for healthy bones and teeth and tends to have major health benefits for the body though several people may suffer from deficiency.

Average age of people in the study had been 70 and like several people of that age, they seemed to have low level of vitamin D even in summer. Dr Klaus Witte, consultant cardiologist, had said that `they spend less time outside and the skin’s ability to manufacture vitamin D also gets less effective, with age and we don’t really understand why that is’. Each day for a year, patients were given either a 100 microgram vitamin D tablet or a sugar pill placebo.

Main Extent – Ejection Fraction

The researchers measured the impact on heart failure, a condition wherein the heart tends to get too weak to pump the blood accurately.The main extent was the ejection fraction which is the amount of blood pumped out of the chambers of the heart with each beat. In the case of healthy adult, the figure seems to be between 60% and 70% though only a quarter of the blood in the heart had been successfully pumped out in heart failure patients.

However, in the case of those taking the vitamin pills, the ejection fraction had increased from 26% to 34%. Dr Witte had informed BBC News website that it was quite a big deal which is as big as one would expect from other more expensive treatments that are used and it’s a stunning effect. He added that it is as cheap as chip with no side effects and a stunning improvement on people already on optimal medical therapy; it is the first time anyone has shown something like this in the last 15 years.

Most of Vitamin D – Sunlight

The study also showed that the hearts of the patient became smaller, a suggestion that they are becoming more powerful and efficient. People over 65, in the UK were advised to take 10 microgram supplement of the vitamin. But Dr Witte dos not think that high dose vitamin D should be routine prescribed just yet. He informed BBC that they are a little bit off that yet not because they do not believe it but the data has shown improvement in heart function, they may show improvements in symptoms and a large study is needed.

It was also not clear how precisely vitamin D tends to improve heart function though it is thought that every cell in the body tends to respond to the vitamin. Most of the vitamin D comes from sunlight but it is also found in eggs, oily fish and is added to some of the foods like breakfast cereals.

Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease – Group of Lung Diseases

Chronic obstructive pulmonary disease COPD is referred to a group lung diseases which tend to block the airflow making the breathing difficult. It is the name given for a collection of lung ailments which include chronic bronchitis, emphysema and chronic obstructive airways disease. People suffering from COPD have breathing problems which is due to the narrowing of their airways known as airflow obstruction. The symptoms include, increasing breathlessness while they are active, frequent chest infection, persistent cough with phlegm and the main cause of this ailment is smoking.

The chances of developing this disease increases on smoking and the length of smoking period. Smoking tends to cause irritation and inflames the lungs which results in scarring and over a period of time, the inflammation leads to permanent changes in the lungs. The walls of the airways tend to get thicken with the development of more mucus. The delicate walls of the air sacs in the lungs get damaged causing emphysema with the lungs losing their normal elasticity while the smaller airways become scarred and narrowed. All these changes result in the symptoms of breathlessness, cough and phlegm which are associated with this disease. There are other cases of this disease which is due to dust, air pollution, fumes and genetic disorders though they are quite rare.

Common Conditions - COPD

Emphysema and chronic bronchitis are considered the two most common conditions which are responsible for COPD. Chronic bronchitis is the inflammation of the lining of bronchial tubes that carries air to and from the lungs and emphysema takes place when the air sacs or alveoli towards the end of the smallest air passage, bronchioles, in the lungs tends to get destroyed gradually. Damage to the lungs due to COPD cannot be changed or reversed though treatment could be helpful in controlling symptoms which could reduce further damage. The symptom of this disease does not often show up till the damage has occurred to the lungs which usually worsen over a period of time. In the case of chronic bronchitis, the main symptom is cough which one tends to have at least three months in a year for two consecutive years while the other signs and symptoms may include:
  • Shortness of breath which is more pronounced during physical activities
  • Wheezing
  • Chest tightness
  • The need to clear the throat first thing in the morning due to excess mucus in the lungs
  • A chronic cough which produces sputum which may be clear, white, yellow or greenish
  • Lack of energy
  • Change in colour of blueness of the lips or fingernail beds
  • Frequent respiratory infections
  • Unintended loss of weight which could occur at a later stage
Test & Treatment 

The following test are done for those suffering from COPD which include –

Pulmonary function test – Spirometry being the most common lung function test wherein at the time of this test the person needs to blow into a large tube which is connected to a spirometer and the machine measures how much air the lungs can hold and how fast one can blow out the air from the lungs. It can detect the disease much prior to the symptoms of the ailment and can also be used to track the progress of the disease as well as monitor on the treatment.

Chest X-ray can portray emphysema which is one of the main causes of COPD and can also identify other lung problems or heart failure if any.

CT scan of the lungs could help in detecting emphysema and determine if one would need a surgery for the ailment and could also be used to check for lung cancer which is also common among individuals suffering from COPD.

Arterial blood gas analysis is a blood rest which measures how well the lungs are bringing oxygen in the blood and leaving carbon dioxide.


For all stage of disease, effective therapy available could control the symptoms and reduce the risk of any complications and help in leading an active life. The essential step in the case of COPD is to quit smoking and reduce the chances of getting worse. Doctors may recommend several types of medication to treat the symptoms of COPD which could be taken on regular basis or as the need arises. There are medications which come in the form of inhaler which tends to relax the muscles around the airways and also relieves cough and shortness of breath, making breathing easier.

Inhaled medications could reduce airway inflammation which could help in prevention of exacerbations. Some side effect could include oral infections, bruising and hoarseness. Oral steroids is given to those with moderate or severe acute exacerbation which prevents further worsening of the disease though these medication could tend to have serious side effect like weight gain, diabetes, cataracts, osteoporosis as well as an increased risk of infection. Antibiotic is also given which fights acute exacerbations though it is not clear whether it is due to its antibiotic effect or the anti-inflammatory properties. Surgery is also another option for some people suffering from COPD.

Cardiomyopathy Disease of Heart Muscle

Cardiomyopathy is a general term for diseases of the heart muscle having many causes, symptoms, signs and treatments. It occurs when the walls of the heart chambers tend to get stretched, stiff or thickened and affects the ability of the heart to pump the blood in the body.

In other rare cases, the muscle tissue is replaced in the heart with scar tissue. As cardiomyopathy tends to get worse, the heart gets weaker and is unable to pump blood through the body to have a normal electrical rhythm which could lead to a failure of the heart or irregular heartbeats known as arrhythmias.

This in turn could cause fluid to accumulate in the lungs, feet, ankles, legs or abdomen. People suffering from cardiomyopathy are at risk of dangerous forms of irregular heartbeats which can lead to cardiac death and the most common type of cardiomyopathy is known as dilated cardiomyopathy. The term cardiomyopathy could theoretically refer to any disease related to the heart and is usually referred to severe myocardial disease which leads to heart failure. Some types of cardiomyopathy are inherited and are seen in children as well as younger individuals.

Different Forms of Cardiomyopathy

In the case of dilated cardiomyopathy, the muscle walls of the heart tend to get stretched and thin and cannot contract or squeeze sufficiently to pump the blood in the body. People with dilated cardiomyopathy are at greater risk of heart failure where the heart fails to pump enough blood to the body at the appropriate pressure.

Besides this, the person is also at a risk of valve problems, blood clots and irregular heartbeat and immediate treatment would be essential. The symptoms of heart failure may cause shortness of breath, extreme tiredness and ankle swelling.

Besides dilated cardiomyopathy, there are other types of cardiomyopathy namely hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy and restrictive cardiomyopathy. A heart transplant may be needed for people with severe heart failure. Cardiomyopathy differs from a heart attack though heart attack also tends to damage the heart muscles but may also be caused due to other reasons.

DilatedCardiomyopathy takes place in people between the age of 20 to 60 years more in men than women and when the heart muscles tend to start stretching and getting thin or dilate it could mean that the heart muscles is not capable of contracting normally and is unable to pump sufficient blood to the body. Over a period of time the heart tends to get weak which could lead to heart failure and other complications.

Hypertrophic cardiomyopathy is considered a very common form of cardiomyopathywhich can affect people of any age group and occurs when the heart muscle cells tend to get enlarged causing the wall of the heart to thicken. This could further block the flow of the blood out of the ventricle and if a blockage takes place, the heart would need to work harder in pumping the blood to the body which in turn could lead to chest pain, dizziness, fainting or shortness of breath. This form of cardiomyopathy could also have other effects on the body.

Arrhythmogenic right ventricular cardiomyopathy is a rare type which takes place when muscle tissue in one area of the heart is replaced with scar tissue thereby disrupting the heart’s electrical signals causing irregular heartbeats. Some of the symptoms may include palpitations together with fainting after doing some physical activity which normally affects young adults and teenagers.

Restrictive cardiomyopathy tends to affect the older group of individuals wherein the heart gets stiff and rigid due to abnormal tissues like scar tissue replacing the normal heart muscles.


There is no cure for this ailment, but it could be kept under control by maintaining a healthy diet, quitting smoking if one is prone to smoking, lose excess weight if overweight, reducing the intake of alcohol, get sufficient sleep, handle stress and ensure that any underlying condition like diabetes is kept under control.

Medical treatments may be needed in order to control the blood pressure, remove any excess fluid, correction of the abnormal heart rhythm or prevent the clotting of the blood. In cases with obstructive hypertrophic cardiomyopathy, the septum which is the wall dividing the left and right side of the heart get thickened, bulging into the main heart chamber.

 In such a case, an injection of alcohol in the heart is given to reduce portion of the muscle in the septum or a septal myectomy or heart surgery is done to remove part of the thickened septum, the mitral valve could be repaired simultaneously if required.

Individual with heart rhythm problems could also have the need of a pacemaker or some similar device that could be implanted to control the abnormal rhythm of the heart. Heart transplant is the last resort when other treatment is not effective and does not give much relief to the patient.
