Introduction The added value of exercise ECG data to traditional risk factors in predicting cardiovascular events remains unclear. Deep learning of ECG signals has demonstrated state-of-the-art ...

Junctional ectopic tachycardia (JET) is a rare arrhythmia presenting either as a primary form1 or more often as a transient phenomenon immediately after heart surgery.2 Congenital JET usually occurs ...

Hypertrophic cardiomyopathy (HCM), the most common inherited cardiac disorder, is defined by unexplained left ventricular hypertrophy. HCM is associated with a range of clinical expressions, including ...

Objective In the majority of studies, the effect of physical activity (PA) on cardiovascular disease (CVD) and mortality is estimated at a single time point. The impact of long-term PA is likely to ...

Atrial fibrillation (AF) is the most common sustained arrhythmia. Approximately seven million people suffer from AF in Europe, and it is likely that several more millions suffer from ‘silent’, ...

Defibrillation has been used to treat disturbances of the cardiac rhythm since the late 1800s.1w1 In order to appreciate the mechanisms of defibrillation, one must also understand the basic ...

The structural and functional abnormalities that lead to cardiac death are coronary artery disease and left ventricular abnormalities related to remodelling (left ventricular hypertrophy, left ...

There is a paucity of studies looking at the natural history of valvular heart disease (VHD) in exercising individuals, and exercise recommendations are largely based on expert consensus. All ...
