Cardiology
1. An arrhythmia in which 2 normal QRS complexes are followed by a PVC; this rhythm usually does not progress to dangerous forms of fast ventricular rhythms; in this rhythm, two VPCs never occur one right after the other.
2. A group of 3 beats, usually a sinus beat followed by 2 extrasystoles Etiology Digitalis toxicity, dizziness, caffeine. See Premature ventricular contraction.

Supraventricular or atrial trigeminy is an impulse formation disturbance characterized by a condition in which every third beat is a supraventricular premature beat (BOLTON, 1975).
All cases demonstrated frequent runs of bigeminy, trigeminy and/or multiple episodes of uni-/multi-focal PVC and were determined by the attending anesthesiologist to require conversion to ECG-gated shock delivery for patient safety.
