Introduction Cardiac arrhythmias are disturbances in the normal rhythm of the heart, ranging from benign premature beats to life-threatening ventricular fibrillation. These disorders occur due to abnormalities in impulse formation, impulse conduction, or a combination of both. While non-pharmacological interventions such as catheter ablation, implantable cardioverter-defibrillators (ICDs), and pacemakers have revolutionized arrhythmia management, antiarrhythmic drugs…

1. Introduction to Cardiac Pharmacology: Principles and Clinical Relevance Cardiac pharmacology is a specialized branch of pharmacology that studies drugs used to prevent, treat, and manage cardiovascular diseases (CVDs) such as hypertension, arrhythmias, ischemic heart disease, heart failure, and thromboembolic disorders. Since cardiovascular disease remains the leading cause of morbidity and mortality worldwide, cardiac pharmacology…
