Antiarrhythmic Drug Therapy to Avoid ICD Shocks
Author(s): Jaber Abboud , Joachim R Ehrlich Added: 3 years ago
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… View more

Brugada syndrome (BrS) is a cardiac disease caused by an inherited ion channelopathy. It was first described by the Brugada brothers in 19921 and is associated with a propensity to develop ventricular fibrillation (VF). Brugada syndrome is characterised by prominent J waves appearing as an ST segment elevation in the right precordial leads. In the latest guidelines, diagnosis of BrS constitutes… View more

Defibrillation Threshold Testing: Current Status
Author(s): Justin Hayase , Duc H Do , Noel G Boyle Added: 3 years ago
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… View more

Since the 1960s, Holter monitoring has been a cornerstone for diagnosing suspected arrhythmias in patients of all ages.1 The most common monitoring systems allow the continuous registration of three or more leads for 24–48 hours; newer Holter monitors allow continuous electrocardiogram (ECG) registration for 2 weeks.1 Extending the time of ECG registration will increase the diagnostic yield of… View more

A Brief History of Cardiac Pacing Electrical stimulation of the heart was used sporadically throughout the 19th century, generating a set of case reports, largely related to attempts to resuscitate people.1 The contemporary field of cardiac pacing emerged in the 20th century (Figure 1). The first use of pacemakers in a modern sense was in the late 1920s when Australian anaesthetist Mark Lidwell… View more
