HEALTHSTREAM TELEMETRY VERSION 3 2026
CERTIFICATION EVALUATION TEST PAPER
QUESTIONS SOLUTIONS GRADED A PLUS
◉ Tele Strip Paper.
Answer: -Small box = 0.04 sec
-Large boxes = 5 x 5 small boxes, 0.20 sec
◉ SA Node Rate.
Answer: 60-100 bpm
◉ AV Node Rate.
Answer: 40-60 bpm
◉ Ventricles / Purkinje Fibers Rate.
Answer: 20-40 bpm
◉ Tele Tracing Waves.
Answer: P-wave
-PR-Interval (PRI) = 0.12 - 0.20 sec
-QRS complex = 0.08-0.12 sec
, T-wave
Q-wave
U-wave
◉ Normal PRI.
Answer: 0.12-0.20 sec (3-5 small squares)
-Indicates AV conduction time
-Measure from P wave start to QRS wave
-Consider heart blocks if abnormal
◉ Normal Etiology SA Node.
Answer: Firing of SA Node causing depolarization of Atria. The
impulse travels from SA node, through internodal pathways to AV
node, where it is delayed for short amount of time. (PRI)
◉ Tele Tracing QRS Complex.
Answer: Q-Wave = 1st Negative Deflection
R-Wave = 1st Postive Deflection
S-Wave= Negative Deflection following R-Wave
◉ Normal QRS Complex.
