Cardiac arrhythmias range from common rhythm disturbances to life-threatening electrical emergencies, yet their diagnosis and management require far more than memorizing ECG patterns. Arrhythmias Explained: An Evidence-Based Guide to ECG Analysis, Heart Rhythm Disorders, Atrial Fibrillation, Ventricular Tachycardia, Bradyarrhythmias, Diagnosis, and Treatment provides a clinically grounded framework for understanding how arrhythmias arise, how they appear on the ECG, how risk is assessed, and how treatment decisions are made. Beginning with normal cardiac electrophysiology, ion channels, conduction pathways, automaticity, triggered activity, and reentry, the book builds systematically toward practical ECG interpretation and advanced rhythm diagnosis. Detailed chapters address atrial fibrillation, atrial flutter, supraventricular tachycardia, accessory pathways, premature ventricular complexes, ventricular tachycardia, ventricular fibrillation, inherited arrhythmia syndromes, sinus node dysfunction, and atrioventricular block. Management is examined with equal depth, including anticoagulation, antiarrhythmic drug therapy, cardioversion, catheter ablation, three-dimensional electroanatomic mapping, pacemakers, implantable cardioverter-defibrillators, and cardiac resynchronization therapy. Dedicated sections address arrhythmias in acute myocardial ischemia, cardiomyopathy, congenital heart disease, pediatric patients, perioperative care, and resource-limited health systems. Clinical reasoning remains central throughout. The text connects ECG findings with myocardial substrate, hemodynamic consequence, structural imaging, genetics, ambulatory monitoring, sudden cardiac death risk, and patient-specific therapeutic decisions. Practical appendices provide rapid-reference material on ECG intervals and measurements, antiarrhythmic drug monitoring, pacemaker and ICD terminology, and acute rhythm-management algorithms. A comprehensive glossary and structured index further support efficient clinical use. Written for medical students, postgraduate trainees, physicians, cardiology professionals, researchers, and clinicians seeking a stronger foundation in electrophysiology, Arrhythmias Explained combines mechanistic understanding with evidence-based clinical application to make complex rhythm disorders more systematic, interpretable, and manageable.
