This book aims to provide a comprehensive guide to the heart's electrical system and its reflection on the ECG. We will explore the anatomy and physiology of the cardiac conduction system, including the sinoatrial node, atrioventricular node, bundle of His, and Purkinje fibers. We will also delve into the mechanisms of cardiac action potentials and conduction pathways, as well as the standard ECG leads and their anatomical correlations.
Through this book, we hope to empower healthcare professionals, students, and researchers with a deeper understanding of the heart's electrical activity and its clinical significance. By mastering the concepts presented herein, readers will be better equipped to interpret ECGs accurately, diagnose cardiac conditions, and provide optimal care for patients.
