Since the 1990s, the publication of several large randomised controlled trials (RCTs) have established the efficacy of implantable cardioverter defibrillator (ICD) therapy in reducing the risk of sudden cardiac death (SCD) in high-risk patients. Collectively these trials have demonstrated a significant all-cause mortality reduction compared with medical therapy alone, for both the primary and…

Implantable cardioverter defibrillators (ICDs) have been used for over 30 years to prevent sudden cardiac death (SCD). The first indications for ICD placement were secondary prevention; later trials demonstrated a primary prevention benefit of ICD therapy in patients at risk of SCD. ICD therapy prolongs life in both patient populations.1 However, the efficacy of an ICD depends on its ability to…

Ventricular arrhythmias are a therapeutic challenge. They occur frequently in clinical practice, are found in patients with and without structural heart disease, and most importantly, are unpredictable and potentially deadly. Patients with a history of sustained ventricular tachycardia (VT) and VF or those at high risk for such arrhythmias, may require an ICD to prevent sudden cardiac arrest…

Device therapy is increasingly employed in the management of complex congenital heart disease (CHD). Bradycardias, most often related to sinus nodal dysfunction (SND) or atrioventricular nodal (AVN) block, may necessitate the implantation of pacing devices, while malignant arrhythmias may be treated by appropriate use of implantable cardioverter defibrillators (ICDs). However, there is a complex…

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…

Motor vehicle travel and driving has become a major component of daily living in the developed world. Sudden incapacity occurring while driving can result in accidents that may be fatal both for the driver and for bystanders. The regulatory approach aims to balance the risk to bystanders against the highly valued individual freedom of motorised mobility. In this article we review some of the…

The ICD is an important therapy for both primary and secondary prevention of sudden cardiac death in selected patients. The role for defibrillation threshold (DFT) testing either intraoperatively or postoperatively has changed significantly over the past few decades, and it is no longer routinely recommended in patients undergoing left-sided transvenous ICD implantation.1–7 The definition of the…

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…
