PPT-Antiarrhythmics Cardiac Arrhythmias

Cardiac arrhythmias are the most common cause of death in patients with a myocardial infarction or terminal heart failure Normal sinus rhythm is dependent on generation of an impulse in the normal sinoatrial SA node pacemaker and its conduction through the atrial muscle through the atrioventricular AV node through the Purkinje conduction system to the ventricular muscle.
