Elements of the cardiac conduction system
WebA system for diagnosing an arrhythmia of a patient comprises: a diagnostic catheter for insertion into the heart of the patient, the diagnostic catheter configured to record anatomic and electrical activity data of the patient; and a processing unit. The processing unit is configured to receive the recorded electrical activity data, and correlate the electrical … WebList in the correct order the major phases of the cardiac cycle following ventricular filling. 1. isovolumetric contraction. 2. ventricular ejection. 3. isovolumetric relaxation. The depolarization of the SA node (from threshold to peak) is due to the inflow of __ and ___ iions. calcium; sodium.
