Explain all the electrical and mechanical events which occur during each measured wave, segment and interval. An electrical event would be membrane polarization: depolarization, repolarization, resting membrane potential, hyperpolarization etc; mechanical events include blood flow, open or closed valves, heart sounds, contraction, relaxation, pressure changes, etc. An example of a complete answer for the P wave is given below. Feel free to use your lecture and/or textbook as a reference to make the connections between ECG and the cardiac cycle. This is a great way to review for the exam and apply what you are learning. P Wave – During the P wave, depolarization is sweeping from the SA node throughout both atria (electrical event). This leads to the beginning of atrial contraction (mechanical event).
