RPSGT ECG Exam Questions with
Correct Answers (VERIFIED)
100% PASS
When analyzing a rhythm strip, it qualifies as being regular when—ANSWER--the PR interval
measures the same
Normal cardiac cycle on ECG—ANSWER--1. P wave: atrial depolarization
2. P-R interval: time required for impulse to travel from atria though conduction system to
Purkinje fibers.
3. QRS wave: ventricular depolarization
4. ST segment: beginning of ventricular repolarization
5. T wave: ventricular repolarization
6. QT interval: time for electrical systole
Premature ventricular contractions (PVC) on ECG:—ANSWER---No P wave
-Bizarre and wide QRS that is premature, followed by long pause
Ventricular tachycardia (VT) on ECG:—ANSWER---15--200 bpm
-Wide, bizarre QRS waves
, -No P waves
Ventricular fibrillation (VF) on ECG—ANSWER---Bizarre, erratic activity without QRS
complexes
Atrial arrhythmias (supraventricular) on ECG:—ANSWER---P wave are abnormal (variable in
shape) or not identifiable (atrial fibrillation)
Impaired coronary perfusion (ischemia or injury) on ECG:—ANSWER---ST segment becomes
depressed
-ST depression can be upsloping, horizontal or downsloping
Acute MI on ECG:—ANSWER--ST elevation
Hyperkalemia—ANSWER---Widens QRS
-Flattens P wave
-T wave becomes peaked
Hypokalemia—ANSWER---Flattens T wave (or inverts)
-Produces a U wave
Which of the following steps is not one of the five-steps of rhythm analysis?—ANSWER--QT
Interval
Which of the following is considered normal range of the QRS complex?—ANSWER--0.06 -
0.10 seconds
Which of the following is considered normal range of the PR interval?—ANSWER--0.12 - 0.20
seconds
