Unmasking Adenosine: The Purinergic Signalling Molecule Critical to Arrhythmia Pathophysiology and Management
Author(s): Gareth DK Matthews , Andrew Grace Added: 3 years ago
The use of adenosine in cardiology is ubiquitous. From arrhythmia to coronary intervention to cardiac imaging, adenosine is an essential part of everyday practice because of its widespread effects on electrophysiology and the coronary vasculature. Electrophysiologists will be most familiar with adenosine for its use in terminating supraventricular tachycardias (SVTs) that are dependent on the… View more

Electrophysiology & Arrhythmia
Author(s): Jean-Baptiste Gourraud , Jason G Andrade , Laurent Macle , et al Added: 3 years ago
Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia observed in clinical practice, occurring in approximately 2 % of the general population.1–3 A progressive increase in both the prevalence and incidence of AF has been demonstrated in recent years, defining AF as a major economic and public health issue.1 The identification of sites of AF initiation and/or maintenance within… View more

Prevention & Chronic Conditions
Author(s): Mark E Josephson Added: 3 years ago
In patients with syncope or episodes of palpitations and heart disease, an electrophysiology study (EPS) may be of value by means of potential induction of sustained ventricular tachyarrhythmias.1,2 Programmed ventricular stimulation may be useful in the context of risk stratification of ischaemic patients with left ventricular ejection fraction (LVEF) 30–40 %, and there has been some evidence… View more

Atrial Tachycardias After Atrial Fibrillation Ablation: How to Manage?
Author(s): Yuan Hung , Shih-Lin Chang , Wei-Shiang Lin , et al Added: 3 years ago
AF is the most common clinical arrhythmia that causes severe adverse cardiovascular events, such as ischaemic stroke and acute heart failure.1 Triggers from the pulmonary vein (PV) have been identified as crucial ectopic sources that initiate AF and pulmonary vein isolation (PVI) is the cornerstone for catheter ablation of AF.2,3 Per the European and US AF guidelines, catheter ablation of AF is… View more

Supraventricular Arrhythmias in Adult Congenital Heart Disease
Author(s): Carina Blomström-Lundqvist , Tatjana S Potpara , Helena Malmborg Added: 3 years ago
With the advent of successful surgical repairs and modern diagnostic techniques, an increasing number of patients with congenital heart disease survive to adulthood. Despite these improvements, the surgical corrective atrial incisions performed during childhood lead to subsequent myocardial scarring that have the inherent risk of harbouring substrates for macro-reentrant atrial tachycardias … View more

Heterogeneous Populations
Author(s): Steven M Markowitz , George Thomas , Christopher F Liu , et al Added: 3 years ago
Pioneering electrophysiology studies in the 1990s defined the anatomical boundaries of typical atrial flutter, identified regions for effective catheter ablation of this arrhythmia and described procedural endpoints to minimise recurrences after ablation. Activation and entrainment mapping demonstrated that typical flutter arises from reentry around the tricuspid annulus.1 Criteria to confirm… View more
