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

Bigeminy is the alternation between a regular heartbeat and extra, skipped heartbeat. People may experience bigeminy as heart palpitations or fluttering. They may describe the sensation as the ...

Paired, identical-looking QRS complexes can be a consequence of many factors, such as every other beat being atrial, a junctional premature beat (atrial or junctional bigeminy), or 3:2 AV ...

Bigeminy can be brought on by a rush of adrenaline. Caffeine and nicotine can sometimes trigger adrenaline production, so avoiding those triggers may help keep your heart beating steadily.

If you have bigeminy (bi-JEM-uh-nee), your heart doesn't beat in a normal pattern. After every routine beat, you have a beat that comes too early, or what's known as a premature ventricular ...

Answer Ventricular bigeminy Explanation. There are clearly extra QRS complexes that are of different morphology compared to the QRS complexes with preceding p waves, ie, the sinus beats. The extra QRS ...

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 ...

The regular arrhythmia occurring at the beginning of the electrocardiogram was identified as ventricular bigeminy. Single ventricular premature complexes (VPCs), as well as pairs and triplets of ...

Periods of sinus bradycardia and ventricular bigeminy were subsequently noted. Figure 1. ... The initial component of the QRS complex may be suggestive of rapid conduction through specialized ...
