The Cardiac conduction system

This week is "electric"! Would your heart really continue beating if it were suddenly torn from your body? What is a cardiac arrhythmia? And why on earth are there so many abbreviations used in cardiology? With the exception of the last one, the answers can be found this week as we explore the conduction system of the heart.

Terms we discuss are; The Sinoatrial (SA) node, Atrioventricular (AV) node, Bundle of His, left and right bundle branches, and the Purkinje fibres. Now you see why we abbreviate..... catchy!
