Conduction System of the Heart: ECG-EKG Quiz:
1. How many basic wave forms are present in one complete cardiac cycle?
2 3 4 5
2. Which of these waves represents ventricular depolarization?
T P QRS S
3. Which of these waves represents atrial depolarization?
4. Which color-coded clip is the “reference” clip?
Green Red Black Yellow
5. Which of these waves conceals atrial repolarization?
6. Which of these is the correct placement of electrode “tabs”?
The tabs should point towards the patient’s navel. The tabs should point towards the patient’s fingers. The tabs should point towards the patient’s elbow. The tabs should point towards the patient’s toes.
7. Which of these is NOT a place where we positioned an electrode?
Electrodes were not attached to the inner surface of the left elbow. Electrodes were not attached to the inner surface of the right wrist. Electrodes were not attached to the inner surface of the left wrist. Electrodes were not attached to the inner surface of the right elbow.

11. Which of these is the first “dip” in a cardiac cycle?
12. Which of these is the second “dip” in the cardiac cycle?
13. Which of these is the second “bump” in the cardiac cycle (the last wave)?
T Q R S
14. Which of these is NOT indicated by an ECG?
Voltage Contraction Relaxation Electrical events
15. Which of these events is concealed in the electrocardiogram?
Ventricular contraction Ventricular relaxation Atrial contraction Atrial relaxation
NOTE: You are responsible for the use and interpretation of the ECG (EKG) computer program as practiced in our laPractical applications such as these are an inherent part of each laboratory activity and exam.
