The sinus rate is actually 68 beats/min — a normal sinus rhythm with atrial bigeminy and not truly a tachycardia. Philip Podrid, MD, is an electrophysiologist, ...

The correct diagnosis is normal sinus rhythm with junctional bigeminy (Figure 2). Figure 2. Courtesy of Philip J. Podrid, MD. Discussion.

Medically reviewed by Jeffrey S. Lander, MD Bigeminy is an irregular heart rhythm where every normal beat is followed by an abnormal one, often due to premature ventricular contractions (PVCs). It ...

Two runs of ventricular bigeminy were recorded (Fig. 1) on the day of the preoperative health check. In this regular arrhythmia, each sinus beat alternates with a VPC for some period 2 , 3 .

When every other QRS complex is a premature atrial contraction, then the rhythm is referred to as “ atrial bigeminy ” as seen in this strip above.. If a PAC occurs when the AV node has not yet ...

1. Atrial fibrillation with a slow ventricular response 2. Right bundle branch block 3. Prolonged QT interval (with normal QTc interval) The QRS complex is irregular and coarse "fibrillatory waves ...
