EP22 – Electrophysiology of the Heart | Anaesthetic Primary Topic | Cardiac Physiology | CT10

Today I'm back with the first topic for Cardiac Physiology – 'Electrophysiology.' This is a huge first topic despite only covering two learning objects. I start by covering the ionic basis of automaticity (01:22) then look at the normal and abnormal process of cardiac excitation (04:02). I briefly then cover the basis of an ECG (12:58), the factors that affect cardiac electrical activity along with the pathway of electrical activity generation in the heart (17:55). Finally, to finish this first mammoth learning objective I describe the mechanical events of the cardiac cycle (21:51). The second learning objective for today cover the process of excitation contraction coupling (28:42) which is favourite of some examiners by linking it to cardiac pharmacology. As always, I end with reviewing the past SAQs, today I have some from the ANZCA and the CICM exams (36:33). Next episode I will go through 'Myocardial O2 Supply and Demand.'  Thanks for listening! As always if you have any feedback let me know
