Cardiac Excitability, Rhythmicity & Conductivity (10-2023) by Dr Khaled A Abulfadle

Learning Objective: 1-Define cardiac excitability & clarify causes of cardiac muscle resting membrane potential. 2-Describe phases & ionic basis of cardiac muscle action potential. 3-Explain excitability changes during cardiac muscle action potential. 4-Clarify the relation between mechanical response and action potential (electrical response) of ventricular muscle fiber. 5-Distinguish factors affecting cardiac muscle excitability. 6-Define automaticity (rhythmicity) and explain pacemaker potential. 7-Differentiate ventricular and pacemaker action potentials. 8-Clarify factors affecting cardiac muscle rhythmicity. 9-Describe the conductive system of the heart. 10-Explain role of AV node as a part of cardiac conductive system. =========================================== Educational Video for Arabic Speakers Medical Students ============================= Links for PDF file: On Website: https://khafadle.ahlamontada.net/t731...
