This engaging book covers a multitude of topics related to heart rhythm disorders (HRDs) and uniquely familiarizes readers with the development of treatment modalities over the past several decades, including the evolution of anti-arrhythmic drugs, pacemakers, defibrillators, and catheter ablation. Organized in ten sections, this title serves as both an archival and a contemporary resource for clinicians. The first section describes the discovery of the circulatory system by William Harvey in 1628 and outlines the development and understanding of HRD since the advent of intra-cardiac electrophysiology. Subsequent sections discuss the historical evolution of abnormal heart rhythms, such as supra and ventricular rhythms and sudden cardiac death, their treatment with drugs, surgery, pacemakers, implantable defibrillators and catheter ablation. Section nine offers a fascinating narration of the clinical evolution of overcoming heart attacks and its impact on HRDs.
