C)bradycardia
D)premature ventricular contractions

Question

Quizplus · Accepted Answer

Ventricular fibrillation is a life-threatening arrhythmia where the ventricles quiver and are unable to contract effectively, resulting in no blood flow to the body. The absence of QRS complexes on an electrocardiogram (ECG) is a hallmark characteristic of ventricular fibrillation. Atrial fibrillation (A) is a rapid, irregular rhythm originating in the atria that produces a chaotic waveform on the ECG. Bradycardia (C) is a slow heart rhythm, but it still produces QRS complexes on the ECG. Premature ventricular contractions (D) are extra heartbeats that originate in the ventricles, producing bizarre-looking QRS complexes on the ECG.
