Lab #10: Cardiovascular Physiology p.3 The Cardiac Cycle and Heart Sounds The electrical signals recorded on an ECG are caused by intermittent periods where the myocardium of the heart undergoes action potentials. These action potentials trigger the myocardium of the ventricles to contract for a period of time and then relax. The resultant
