introduction brugada syndrome (brs) is an autosomal-dominant inherited cardiac arrhythmia that occurs due to sodium channelopathy and increases sudden cardiac death due to episodes of polymorphic ventricular tachyarrhythmia. it is characterized by st-segment elevation in the right precordial leads and right bundle branch block (rbbb) pattern. we herewith present a case of brugada syndrome with ...

Many studies have shown that the relationship between alcohol consumption and most cardiovascular diseases is U-shaped, with nondrinkers and heavier drinkers having higher risks than moderate drinkers. However, the association between cardiac arrhythmias and acute alcohol consumption is not well understood. We set up several experimental arrhythmia animal models to examine the effects of acut...

In this paper, an automatic detecting algorithm for QRS complex detecting was applied for analyzing ECG recordings and five criteria for dangerous arrhythmia diagnosing are applied for a protocol type of automatic arrhythmia diagnosing system. The automatic detecting algorithm applied in this paper detected the distribution of QRS complexes in ECG recordings and related information, such as hea...

Many dietary supplements promise to improve physical and mental functioning, but caffeine, an age-old food component, is one of the few that delivers. Caffeine makes its consumers awake and alert, and it improves performance (1). Therefore, coffee could be called a functional food. But is it safe? If coffee were discovered today, it would probably be regarded, in the European Union’s terminolog...

Given the unique interventional emphasis in our specialty, Teaching Rounds in Cardiac Electrophysiology has frequently centered on the pearls and pitfalls associated with electrogram analysis and complications of lead implant extraction or ablation and in mapping complex arrhythmia circuits. In this issue of Circulation: Arrhythmia and Electrophysiology, Fabrizio et al, in a refreshing departur...

Inherited cardiac arrhythmia syndromes have received a lot of attention in recent years, particularly the molecular genetic basis, which has been unraveled to a great extent in the past years. Disease entities have been subdivided based on their causal gene defect, which, indeed, has been shown to impact on disease expression, clinical characteristics, prognosis and treatment. This particularly...

The electrocardiogram (ECG) signal has great importance in diagnosing cardiac arrhythmias. In this paper we have compared three classifiers on the basis of their accuracies for the detection of arrhythmia. The algorithms that are used for classification are supervised machine learning algorithm. The performance of the classifier depends upon its accuracy rate. The classifiers used are Nearest N...

Lethal cardiac arrhythmias in individuals with structurally normal heart are often caused by variants in genes that encode cardiac ion channel and -subunits (102). Common inherited arrhythmia syndromes include the congenital long QT syndrome (LQTS), Brugada syndrome (BrS), short QT syndrome (SQT), and catecholaminergic polymorphic ventricular tachycardia (CPVT) (76). Moreover, inherited mutatio...

Abnormal foci in the auricles, from which the cardiac impulse may arise, beget various types of arrhythmia. Three main groups may be distinguished, namely, ectopic beats, auricular tachycardia (of slower or faster rate), and auricular fibrillation. Although the deranged auricular function is fundamentally similar in each variety, there are reasons for regarding the groups as separate nosologica...
