The number of invasive electrophysiological procedures is steadily increasing in Western countries, as techniques advance and the age of the population increases. Gender exerts a profound influence on the epidemiology, pathophysiology and clinical presentation of many cardiac rhythm disorders, and all these factors may affect the outcome of invasive electrophysiological procedures. Disturbingly,…

Lightning strikes between clouds and ground objects occur when the difference in electrical potential between the two is greater than 30,000 Volts, as thus they are able to exceed the atmospheric electrical resistance, generating currents that vary from 30,000 to 100,000 Amperes, and lasting between 0.1–0.001 seconds. As per data from the Lightning Imaging Sensor (LIS)-equipped satellite…

Implantable cardiac devices such as implantable cardioverter- defibrillators (ICDs) and cardiac resynchronisation therapy (CRT) devices lead to improved survival and better clinical outcomes in appropriately selected patients with heart failure (HF) with a reduced ejection fraction (EF). Although there are significant sex differences in the aetiology, pathophysiology and clinical course of HF,…

An estimated 180,000–300,000 sudden cardiac deaths (SCD) occur in the US annually.1,2 Worldwide, sudden and unexpected cardiac death is the most common cause of death,2 accounting for 17 million deaths every year with SCD accounting for 25% of these. The accepted definition of SCD is death that occurs within one hour of onset of symptoms in witnessed cases, and within 24 hours of last being seen…

Ventricular arrhythmias remain a major contributor to cardiac morbidity and mortality worldwide, despite ongoing research and implementation of novel therapeutic interventions. Modern management of patients with ventricular arrhythmias requires a multidisciplinary team approach, especially in complex presentations with a background of multiple medical comorbidities.1,2 Such teams may include…

Since its initial description by Jervell and Lange-Nielsen in 1957,1 congenital long QT syndrome (LQTS) has been the most investigated cardiac ion channelopathy. A prolonged QT interval on the surface ECG is a surrogate measure of prolonged ventricular action potential duration (APD).
Congenital as well as acquired alterations in certain cardiac ion channels can affect their currents in such a…

Catheter ablation has moved from ablation of ‘simple’ substrates like accessory pathways,1 atrioventricular nodal re-entrant tachycardias (AVNRTs)2 and re-entrant or focal tachycardia (of either ventricular or atrial origin)3–5 in recent years to more complex arrhythmias such as atrial or ventricular tachycardia (VT) or fibrillation.6–8 Even patients with complex congenital heart disease that may…
