Atrioventricular nodal reentrant tachycardia (AVNRT) denotes re-entry in the area of the AV node, and represents the most common regular arrhythmia in the human.1 Although several models have been proposed to explain the mechanism of the arrhythmia in the context of the complex anatomy and the anisotropic properties of the atrioventricular (AV) node and its atrial extensions (see Figure 1),2 the…

Accurate substrate characterisation is important for depicting scar-related re-entrant tachycardia to optimise ablation targets and strategies. The underlying substrate can be analysed using electrogram (EGM) characteristics, such as low voltage, local abnormal voltage activity (LAVA), evoked potentials or late potentials, conduction analysis in sinus rhythm or differential pacing, or using…

Catheter ablation of AF has become an established therapy and may have the potential to cure this most commonly encountered sustained arrhythmia. Previous studies have demonstrated that pulmonary veins (PVs) are a major source of the ectopic beats that initiate AF. PV isolation in patients with symptomatic paroxysmal AF refractory to antiarrhythmic drugs is effective; however, it is difficult to…

Radiofrequency (RF) catheter ablation is currently the treatment of choice in patients with accessory pathways (APs) and Wolff– Parkinson–White syndrome, and is shown to have a success rate >95 %.1 APs usually have endocardial ventricular and atrial insertions, located close to the atrioventricular valve rings, making most endocardial catheter ablation procedures relatively straightforward and…

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,…

Since the first catheter ablation for cardiac arrhythmia more than three decades ago, ablation technology has continually evolved at a rapid pace. Much of the early progress in the field was made in ablation of supraventricular tachycardias. Following a seminal study from Haïssaguerre et al.1 in 1998, which demonstrated that pulmonary vein triggers are important sources of atrial fibrillation (AF…
