The ideal pacing site in the ventricle(s) of patients with atrioventricular (AV) block has been debated for years. Despite considerable technological advances, the optimal ventricular pacing site to mimic normal human ventricular physiology and attain the best haemodynamic response remains elusive.1 Prolonged ventricular dyssynchrony induced by long-term right ventricular (RV) apical pacing is… View more

Dr Pugazhendhi Vijayaraman (Geisinger Heart Institute, Mountain Top, PA, US) shares the results from the Left Bundle Branch Pacing for Cardiac Resynchronization Therapy study. The aim of the study was to assess the feasibility and outcomes of LBBP in CRT eligible patients in an international, multicenter, collaborative study. Questions: 1.What was the rationale for the study? 2.What patients… View more

Sustained ventricular tachycardia (VT) and ventricular fibrillation (VF) are typically a manifestation of significant structural heart disease and often associated with a high risk of sudden cardiac death. Implantable cardioverter defibrillators (ICDs) remain the mainstay of therapy for prevention of sudden cardiac death associated with these arrhythmias.1 However, ICDs treat the arrhythmia after… View more

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
