His bundle pacing in humans was first described in 1970 by Narula et al.1 They demonstrated that it was possible to stimulate the His bundle to produce normal physiological ventricular activation via the His-Purkinje system. However, the first report of permanent His bundle pacing, by Deshmukh et al., did not occur until 2000.2 In that study, His pacing was performed in a series of patients with… View more

Cardiomyopathies are heterogeneous heart muscle disorders with a wide range of aetiologies and clinical manifestations.

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

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,… View more

Cardiac arrhythmias during pregnancy pose a serious threat to the health of both mother and foetus. Women with established tachyarrhythmias, congenital heart defects or channelopathies have the highest risk for development of arrhythmias.1,2 They also develop de novo or occur in women without apparent heart diseases. Tachyarrhythmias, including both supraventricular and ventricular tachycardias,… View more
