NCCT ECG Practice Test Exam Questions
And Answers 2025 Update.
The p wave should always be upright in leads 1 and 2 - Answer✔what would be considered a
cardinal feature of sinus rhythm?
U - Answer✔what is a small wave (similar to the P wave) that sometimes appears after the T
wave, and is thought to represent late repolarization of the Purkinje fibers in the ventricles?
sick sinus rhythm - Answer✔a disturbance of SA nodal function that results in a markedly
variable rhythm is known as
atrial fibrillation - Answer✔what term best describes a cardiac condition that demonstrates a
sinus rate of 250 to 350 beats per minute
T - Answer✔which wave represents ventricle depolarization
ventricular tachycardia - Answer✔which of these ECG findings indicates a pulse greater than
100 beats per minute with at least three irregular beats in a row
atrial depolarization - Answer✔the p wave is indicative of
premature atrial contraction with pvcs - Answer✔what best describes this rhythm strip
trigeminy pvcs - Answer✔what best describes this rhythm strip
sinus bradycardia - Answer✔what best describes this rhythm strip
isolated pvc - Answer✔what best describes this rhythm strip
diastole - Answer✔occur when the ventricle relax, and the blood flows into the atrium from the
vena cava and pulmonary
exposure to interference - Answer✔what is the LEAST likely to cause under-sensing in the ECG
over-sensing - Answer✔drug therapy, hyperkalemia, Twiddler's syndrome, and battery
depletion can all be occasional causes of ECG ________.
