Pacemaker AV interval vs PV interval AV interval indicates the paced atrioventricular interval and PV interval indicates sensed atrioventricular interval. This means that the ‘A’ of AV interval
Leadless pacemakers Weakest link in the pacemaker system is considered to be its lead, sometimes called it Achilles heel. This is because the lead system is prone for
Subcutaneous ICD (Implantable Cardioverter Defibrillator) Subcutaneous ICD (S-ICD) is the term used to designate ICDs which are purely subcutaneous, without any intracardiac leads. It was designed aiming to

When not to implant an ICD? There are certain situations when the implantation of an implantable cardioverter defibrillator may not be ideal. Some of the following situations may
Downside of right ventricular apical pacing Right ventricular apical pacing, the usual method of pacing the right ventricle in single chamber and dual chamber pacing, can be deleterious
Can heparin be prothrombotic? Unfractionated heparin can theoretically make platelets more reactive to activation by other platelet function agonists such as adenosine diphosphate. Heparin can bind to Glycoprotein
