Polymorphic Ventricular Tachycardia Storm After Coronary Artery Bypass Graft Surgery: A Form of 'Angry Purkinje Syndrome'.

Background: Polymorphic ventricular tachycardia (PMVT) is a highly lethal arrhythmia which is commonly caused by acute myocardial ischaemia. PMVT mediated by short-coupled ventricular ectopy patients with ischaemic heart disease but in the absence of acute ischaemia may relate to transient peri-infarct Purkinje fibre irritability and has been termed 'Angry Purkinje Syndrome'.

Methods: We present a case series of three patients with PMVT storm 3-5 days following coronary artery bypass graft surgery (CABG).

Incidence of Premature Lead Failure in 2088 Tendril Pacing Leads: A Single Centre Experience.

Background: Recent reports describe a high rate of premature lead failure in the St Jude/Abbott Tendril 2088 (St. Jude Medical Inc., St.

An Update on Anticoagulation in Atrial Fibrillation.

Cerebrovascular accidents related to atrial fibrillation (AF) are potentially preventable with anticoagulation. Until recently, warfarin was the only proven anticoagulant to be effective in stroke prevention, however the novel, direct acting oral anticoagulants (DOACs) are now available, triggering a paradigm shift in treatment philosophy. Today, physicians need to consider in which patients anticoagulation should not be used rather than, as in the past, deciding in which patients it should be used.

Atrial response to ventricular antitachycardia pacing discriminates mechanism of 1:1 atrioventricular tachycardia.

Background: Inappropriate shocks from implantable cardioverter defibrillators (ICD) remain a significant clinical problem despite device discrimination algorithms. The atrial response to antitachycardia pacing (ATP) may determine the mechanism of 1:1 A:V tachycardia.

Methods: For this study we refer to sinus tachycardia, atrial tachycardia (AT), atrial fibrillation, and flutter as atrial tachycardia (AT), and all other tachycardia as "non-AT.
