Function of intrinsic conduction system

WebIntrinsic regulation: In the early 1900's Otto Frank and Earnest Starling independently published findings showing that if you increase the end-diastolic volume, stroke volume increases, without any neural or endocrine input. In other words, if venous return increases (increased end-diastolic volume), cardiac output increases. They correctly observed that … WebThe electrical stimulus travels down through the conduction pathways and causes the heart's ventricles to contract and pump out blood. The 2 upper chambers of the heart (atria) are stimulated first and contract for a short …
