Procedure 1 Identifying Waves of an ECG Let's start by correlating the waves on the ECG with the electrical activity occurring in the electrical events taking place in cardiac cells at each of the six points in the ECG in Fig. 19.8. Provide your answers in the answer lines provided. Do remember though that the ECG shows only electrical activity, not physical contractions. A heart can have electrical activity but not be beating.

The figure shows the pressure changes in an individual's heart during the cardiac cycle. Figure 3: Pressure (mm Hg) Left atrium Left ventricle Time (s) Calculate the heart rate for the individual shown in Figure 3 (beats per minute).
Arrange these elements of the intrinsic conduction system in the order that a depolarizing impulse travels during normal heartbeat: Rank from first to last: Do not overlap any tiles. AV node Purkinje fibers SA node AV bundle Internodal pathways Bundle branches First Element Depolarized Last Element
