Question

Select all that apply. 1. Three premature ventricular contractions in rapid succession
2. Heart rate 150 beats per minute
3. Absent P waves
4. Absent PR interval
5. Undetectable QRS complex

Answer 1

1,2,3,4
Rationale 1: Ventricular tachycardia is a run of three or more premature ventricular contractions in rapid succession.
Rationale 2: In ventricular tachycardia, the heart rate is between 110 to 250 beats per minute.
Rationale 3: In ventricular tachycardia, the P waves are usually absent.
Rationale 4: In ventricular tachycardia there is no PR interval.
Rationale 5: There is a QRS complex in ventricular tachycardia.
