Catheter ablation of AF has shown steady growth over the past two decades with a nearly 15 % annual increase in the US.1 This growth can be attributed in large part to four factors: an increase in operators and institutions performing the procedure;2 a steady rise in AF prevalence, which is predicted to reach 12 million in the US by 2030;3 a larger spectrum of AF patients with more complex atrial… View more

During the last decade, catheter ablation has become a highly effective treatment option for the cure of symptomatic, drug-resistant atrial fibrillation (AF). Despite the diversity of individual ablation strategies, all of them have something in common: the ablation is performed either within or around the ostia of the pulmonary veins (PV). This practice focused the authors' attention on anatomy… View more

Applications of Machine Learning in Cardiac Electrophysiology
Author(s): Rahul G Muthalaly , Robert M Evans Added: 3 years ago
Artificial intelligence (AI) has recently become a popular term in the technological world. AI refers to the simulation of human intelligence with the capacity for achieving goals within computers. Machine learning (ML) – a subtype of AI – refers to a statistical model that is able to independently learn to make inferences on new data based on data it has previously analysed. ML has markedly… View more

It has been considered that an interatrial block exists when there is a delay of conduction in some part of the Bachmann’s bundle zone.1 The interatrial blocks are the most frequent and well-known blocks at atrial level. These are expressed in the electrocardiogram (ECG) by the presence of a P wave duration that equals or exceeds 120 milliseconds and presents usually a bimodal morphology,… View more

AF is the most common sustained cardiac rhythm disturbance.1 Worldwide, there is an estimated 33.5 million people with AF as of 2010.2 While there are multiple estimates, the yearly incidence in the US is expected to grow, for example, from 1.2 million cases in 2010 to 2.6 million cases in 2030 and upwards of 6–12 million cases by 2050.1,3 It is associated with increased morbidity and mortality4… View more

The introduction of cardiac electroanatomic mapping systems in the mid-1990s has permitted investigators to record intracardiac electrograms (EGMs) with accurate spatial localisation in 3D.1 These 3D mapping systems have enabled the display of the cardiac chambers as an anatomical shell upon which voltage, or activation, information can be displayed. Most commonly, colour is used to represent the… View more

The origin of idiopathic ventricular tachycardia (VT) or symptomatic premature ventricular contractions (PVCs) from papillary muscle (PM) was first described in 2008 as a distinct clinical syndrome by a group from Birmingham, Alabama, US.1 Out of 290 patients ablated for idiopathic VT or symptomatic PVCs, seven patients were recognised who had the ablation site at the base of the posteromedial PM… View more
