Question # 1
The electrical events associated with each normal heartbeat include all but:
A. Exchange of ions across the cell membrane resulting in myocardial depolarization
B. Spontaneous generation of an impulse in the pacemaker cells, i.e., the SA node
C. Return of the myocardial cell to its resting state (repolarization)
D. Propagation of the electrical impulse from the SA, thru the AV node, and finally thru the Purkinje system
E. Spontaneous generation of an impulse in the pacemaker cells of the ventricles Correct
Question # 2
The following is characteristic of the sinoatrial (SA) node:
A. Has an intrinsic rate of 40 bpm to 60 bpm
B. Is capable of spontaneously generating an electrical impulse Correct
C. Is located near the interatrial septum, or junction
D. Serves as a gatekeeper, delaying impulses to allow time for the ventricles to fill
Question # 3
The ECG is from a 71-year-old in the CCU. It shows:
A. Sinus bradycardia
B. First-degree heart block
C. Third-degree heart block Correct
D. Atrial fibrillation
E. Atrial fibrillation
Question # 4
A 67-year-old was admitted to the ICU because of chest pain. The night nurse printed out the ECG strips from four

, different leads and they are shown below. The patient most likely developed:
A. Ventricular fibrillation
B. Ventricular tachycardia Correct
C. Atrial flutter
D. Torsades de pointes
Question # 5
A 29-year-old woman presents to the ED with complaints of palpitations, vague chest pain, and diaphoresis. She claims
that she got scared when a man approached her on the street and demanded her purse. The resulting panic attack led
to these symptoms. However, she is worried because the palpitations have now been going on for at least 60 minutes.
Her vitals are stable, and her ECG strip is shown below. She most likely has:
A. Atrial tachycardia Correct
B. Ventricular tachycardia
C. MI
D. Atrial flutter
Question # 6
A 67-year-old woman treated with hydrochlorothiazide for her hypertension presents to the ED with dizziness. Blood
work reveals hypokalemia. The ECG which was done is shown below. She most likely has developed:
A. Peaked T waves
B. Torsades de pointes Correct
C. Atrial tachycardia
D. Ventricular tachycardia
Question # 7
A 57-year-old man in the ICU has a BP of 65/35 with pulse oximetry 86% on 100% oxygen facemask. The patient
becomes unresponsive and pulseless with the following rhythm. The next step in his management is:
