cardiac monitoring certification
SECTION 1: CARDIAC ANATOMY & PHYSIOLOGY
Question 1
Which of the following ECG waveforms represents ventricular
depolarization?
A. P wave
B. QRS complex
C. T wave
D. U wave
Answer: B. QRS complex
Rationale: The QRS complex represents ventricular depolarization—the
electrical activation of the ventricles that triggers mechanical
contraction. The P wave represents atrial depolarization, the T wave
represents ventricular repolarization, and the U wave (when present) is
thought to represent repolarization of the Purkinje fibers or papillary
muscles .
Clinical Pearl: Remember: "P" for "Pumping" (atrial contraction),
"QRS" for "Ventricular" (ventricular contraction), and "T" for "Tired"
(ventricular recovery/resting).

Question 2
The inherent (intrinsic) rate of the SA node is:
A. 20-40 beats per minute
B. 40-60 beats per minute
C. 60-100 beats per minute
D. 100-180 beats per minute
Answer: C. 60-100 beats per minute
Rationale: The sinoatrial (SA) node is the normal pacemaker of the
heart with an inherent firing rate of 60-100 beats per minute. The AV
junction has an inherent rate of 40-60 bpm, and the Purkinje
fibers/ventricles have an inherent rate of 20-40 bpm. This hierarchy
ensures that the fastest pacemaker (SA node) normally controls the heart
rate .
Clinical Pearl: Memorize the escape rhythm rates: SA node 60-100, AV
junction 40-60, ventricles 20-40. This helps identify the origin of escape
rhythms.
Question 3
The inherent rate of the AV junction is:
A. 20-40 beats per minute
B. 40-60 beats per minute
C. 60-100 beats per minute
D. 100-180 beats per minute
Answer: B. 40-60 beats per minute
Rationale: The atrioventricular (AV) junction, which includes the AV
node and bundle of His, has an inherent firing rate of 40-60 beats per
