Applied Cardiovascular Anatomy, Embryology and Physiology Embryological development of the heart and great vessels; fetal circulation and transition at birth; gross structure and position of the heart; chambers, septa, valves and fibrous skeleton; anatomy and properties of cardiac muscle; coronary arterial and venous circulation; blood and nerve supply to the heart; autonomic innervation; major cardiac and systemic vessels. Cardiac electrophysiology: transmembrane potential, resting membrane potential, depolarization and repolarization, phases of the cardiac action potential, refractory periods, automaticity, excitability, conductivity and contractility. Mechanical activity: cardiac cycle, pressure-volume relationships, stroke volume, ejection fraction and cardiac output. Regulation of heartbeat; intrinsic regulation including Frank-Starling mechanism; extrinsic/autonomic and hormonal regulation; regulation of peripheral circulation, vascular tone and blood pressure
