Book Abstract

The landscape of cardiac pacing has transformed remarkably since the first implantable pacemaker in 1958, evolving from large, external devices to highly sophisticated implants that restore heart rhythm with increasing safety and precision.This book explores the progression of pacemaker technology, the patient and clinical benefits, and the future horizons of cardiac rhythm management. Early electronic pacemakers, including epicardial designs and isotope-powered devices, laid the groundwork for modern lithium-battery generators and programmable microprocessor-driven systems. The subsequent development of dual-chamber pacing and cardiac resynchronization therapy (CRT) enhanced hemodynamic performance and clinical outcomes. Addressing the complications associated with transvenous leads and generator pockets, the rise of leadless pacemakers
