The rhythm in which three or more PVCs arise in sequence at a rate of greater than 100 beats per minutes is ventricular:

B) asystole.
C) torsades.
D) fibrillation.

Question

Quizplus · Accepted Answer

This describes ventricular tachycardia, as it is a rhythm that involves three or more consecutive premature ventricular contractions (PVCs) occurring at a rate greater than 100 beats per minute. Asystole is the absence of any electrical or mechanical activity in the heart and would not involve PVCs. Torsades de pointes is a specific type of ventricular tachycardia characterized by a twisting of the QRS complex on the ECG, and fibrillation is an irregular and chaotic rhythm of the heart.
