Brugada syndrome (BrS), one of the most common causes of sudden cardiac death (SCD) in normal structural heart individuals, is a young entity in modern medicine. BrS was first characterised in 1992 by Brugada et al. as a distinct syndrome with “right bundle branch block, persistent ST elevation in precordial leads V1 to V2–3 and sudden cardiac death”.1 The true prevalence of BrS is not clearly… View more

The interplay between the central nervous system and cardiac electrophysiology is fundamental, and becomes obvious each time one’s pulse quickens in response to stress. Normally, cardiac neurohormonal regulation is accomplished through the balanced effects of sympathetic and parasympathetic autonomic stimulation, along with the hormonal regulation of the renin-angiotensinaldosterone system (RAAS)… View more

Multimodality Imaging to Guide Ventricular Tachycardia Ablation in Patients with Non-ischaemic Cardiomyopathy
Author(s): Ling Kuo , Jackson J Liang , Saman Nazarian , et al Added: 3 years ago
Catheter ablation has been increasingly used as a treatment for refractory ventricular tachycardia (VT) in patients with non-ischaemic cardiomyopathy (NICM). However, ablation outcomes tend to be quite variable because of the heterogeneity of the aetiology for the NICM and associated VT substrate in these patients.1–3 Patients with NICM can be sub-classified based on specific genotypic and… View more

The concept of post-extrasystolic potentiation (PESP), which describes the phenomenon of increased contractility of the beat following an extrasystole, has intrigued physiologists and clinicians for more than 120 years. Since its first description in 1885 by Oskar Langendorff,1 PESP has become a widely debated concept, not only for its fundamental basis but also because of the potential… View more

In 1885, Oscar Langendorff was the first person to describe the increase in contractility (‘Pulsverstärkung‘) that follows an extrasystole.1Langendorff experimented with spontaneously beating isolated frog hearts. He recorded the heartbeats by using a lever that transferred the contractile movements of the heart to a rotating drum. Electrical stimulation resulted in premature contractions that… View more

The structural and/or functional abnormality of the cardiac electrovascular system is the most common cause of world mortality accounting for 29.0 % of deaths, followed by infectious diseases (16.2 %) and cancers (12.6 %) (WHO 2008 report). 1 Abnormalities in the cardiac electrical system (arrhythmias and sudden death) and/or mechanical function (heart failure) constitute one of the major causes… View more
