NYU Langone EKG Exam Questions &
Answers 2024/2025
A delayed conduction of the AV node is manifested by a:
a. prolonged PR interval
b. widened QRS
c. inverted P wave
d. absence of a P wave - ANSWERSa. prolonged PR interval
Which of the following waveforms represent the electrical event that should initiate ventricular
contraction? - ANSWERSQRS complex
What is the normal range of the PR interval? - ANSWERS0.12-0.20
What is the normal length of the QRS interval? - ANSWERSbelow 0.12
What bpm rate is Sinus Tachycardia on a strip? - ANSWERS101-160 bpm
Which of the following describes a cells ability to spontaneously generate an impulse? -
ANSWERSautomaticity
Which node independently conducts a rate of 40-60 in an adult patient? - ANSWERSAV node
Which node independently conducts a rate of 60-100 in an adult patient? - ANSWERSSA node 'the
pacemaker of the heart'
What does the T-wave represent? - ANSWERSventricle repolarization
, What is the normal PQRS ratio? - ANSWERS1:1
What is the rate on a strip for sinus bradycardia? - ANSWERSless than 60 bpm
How do you calculate the rate on a strip? - ANSWERSmultiply the number of QRS's by 10
*pay attention to marks on strip to count right*
How to differentiate between normal sinus rhythm and sinus arrhythmia - ANSWERSthe distance
between each R (peak in QRS wave) is different and NOT the same within a strip
the activation of BLANK system causes in a release in epinephrine which results in an increase in heart
rate, blood pressure, and cardiac output - ANSWERSsympathetic nervous system
the QRS on an EKG corresponds to which of the following electrical events:
a. ventricular depolarization
b. ventricular repolarization
c. atrial repolarization
d. atrial depolarization - ANSWERSa. ventricular depolarization
Inefective atrial contractions are associated with which rhythm
a. normal sinus with PAC
b. normal sinus with PVC
c. ventricular fibrillation
d. atrial fibrillation - ANSWERSd. atrial fibrillation
How can you tell a strip with normal sinus rhythm with PAC (premature atrial contraction is occurring)? -
ANSWERSThe P wave comes EARLY.
P waves occur when the atria contracts followed by the QRS and T waves. You know a PAC is occurring
when the PQRST segment happens too soon after the last PQRST.
