The incidence of ventricular arrhythmias is often related, within an individual, to the rate of their underlying sinus rhythm (heart rate). The direction of this relationship is generally considered to entail some prognostic significance: whereas ectopic activity suppressed by tachycardia is assumed to be benign, an arrhythmia enhanced by tachycardia is regarded with more concern. Is this…

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…

Despite the clear improvements in clinical outcomes brought about by medical therapy with β-blockers, ACE inhibitors and aldosterone antagonists, as well as by device therapy with cardiac resynchronisation, many patients with chronic heart failure (HF) remain symptomatic despite optimal medical therapy. Symptomatic HF can have devastating consequences for the quality of life of individuals, and…

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…

The Risk of Atrial Arrhythmias in Inherited Primary Arrhythmia Syndromes
The inherited primary arrhythmia syndromes (IPAS) are a heterogeneous group of diseases caused by mutations in genes encoding for cardiac ion channels. People affected by one of these inherited diseases have no overt structural cardiac abnormalities but are at higher risk of sudden cardiac death due to the occurrence of…

Short QT syndrome (SQTS) is a rare, inheritable channelopathy of the heart characterised by abnormally short QT intervals on the electrocardiogram (ECG) and an increased propensity to develop atrial and ventricular tachyarrhythmias in the absence of structural heart disease.1,2 SQTS was first described as a new clinical entity by Gussak et al. in 2000.1 Until then shortening of the QT interval…

With the advent of successful surgical repairs and modern diagnostic techniques, an increasing number of patients with congenital heart disease survive to adulthood. Despite these improvements, the surgical corrective atrial incisions performed during childhood lead to subsequent myocardial scarring that have the inherent risk of harbouring substrates for macro-reentrant atrial tachycardias …
