RPSGT ECG Exam Questions with Correct Answers (Grade A+)
Question 1: When analyzing a rhythm strip, it qualifies as being regular when
Answer: the PR interval measures the same
Question 2: 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
Question 3: Premature ventricular contractions (PVC) on ECG:
Answer: -No P wave -Bizarre and wide QRS that is premature, followed by long pause
Question 4: Ventricular tachycardia (VT) on ECG:
Answer: -15--200 bpm -Wide, bizarre QRS waves -No P waves
Question 5: Ventricular fibrillation (VF) on ECG
Answer: -Bizarre, erratic activity without QRS complexes
Question 6: Atrial arrhythmias (supraventricular) on ECG:
Answer: -P wave are abnormal (variable in shape) or not identifiable (atrial fibrillation)
Question 7: Impaired coronary perfusion (ischemia or injury) on ECG:
Answer: -ST segment becomes depressed -ST depression can be upsloping, horizontal or downsloping
Question 8: Acute MI on ECG:
Answer: ST elevation
Question 9: Hyperkalemia
Answer: -Widens QRS -Flattens P wave -T wave becomes peaked

, Question 10: Hypokalemia
Answer: -Flattens T wave (or inverts) -Produces a U wave
Question 11: Which of the following steps is not one of the five-steps of rhythm analysis?
Answer: QT Interval
Question 12: Which of the following is considered normal range of the QRS complex?
Answer: 0.06 - 0.10 seconds
Question 13: Which of the following is considered normal range of the PR interval?
Answer: 0.12 - 0.20 seconds
Question 14: Which feature is most closely associated with ventricular rhythms?
Answer: Absence of P waves and wide & bizarre QRS complexes
Question 15: Bigeminy PVC's are occur how often in a cardiac tracing?
Answer: Every second complex
Question 16: What is the difference between Accelerated Idioventricular Rhythm and Ventricular
Tachycardia?
Answer: Heart rate greater than 100 bpm
Question 17: What is another name for Run of Ventricular Tachycardia?
Answer: Triplet or Salvo PVC's
Question 18: SINUS ARRHYTHMIA
Answer: PT'S EKG TRACING SHOWS AN IRREGULAR R-R RHYTHM WITH NO VISIBLE
ALTERATIONS TO THE P, QRS, AND T WAVES,
Question 19: Z PVC
Answer: EKG RHYTHM CAN BE DESCRIBE AS RAPID, BIZARRE, WIDE QRS COMPLEXES WITH
NO P WAVES
