Describe the parts of the electrocardiogram (ECG) and explain how these electrical events are related to the mechanical events of the cardiac cycle. Reference the Wigger’s diagram. Start at the P-wave and go through to the T-wave. Make sure to clearly state what each wave, interval, and segment represent. Make sure to clearly state the general rule concerning the timing of electrical and mechanical events as well as give specific examples. Mention P wave, QRS complex, T wave, PR interval, R-R interval, PR segment, ST segment, conduction system of the heart, autorhythmic cardiac cells, contractile cardiac cells, depolarization, repolarization, atria, ventricles, atrioventricular node.
