Match the components of an electrocardiogram (ECG) with the events of the cardiac conduction system, systole and diastole (some answers may be used more than once) SA node produces an action potential atria contract action potential propagates triggering the AV node ventricles contract ventricles relax and repolarize ventricular systole; the sum of ventricular activity in a single cardiac rhythm (heart beat) A. Q-T interval B. T wave C. P wave D. QRS complex

Step 1
SA node produces an action potential - This event occurs during diastole, when the heart is relaxed and the atria are filling with blood. Show more…

The Cardiac Conduction System and the Electrocardiogram (ECG/EKG) 1) Define the following terms: a) Depolarization b) Repolarization c) Systole d) Diastole 2) Label each structure on the diagram. Next to the image, describe the path of the electrical signal. Sinoatrial (SA) node Atrioventricular (AV) node AV Bundle of His Right and left bundle branches Purkinje fibers

ECG & HEART SOUNDS 1. The P wave and the QRS complex represent depolarization of the atrial and ventricular muscle, respectively. Why does the QRS complex have the larger amplitude? 2. In the Analysis, you calculated heart rate averaged over 15 seconds and instantaneous heart rates. Explain any differences between these values. 3. Are the amplitudes and durations of the P wave and QRS complex related to the size and thickness of the atria and ventricles?
