| bigeminy | Pairing; especially, the occurrence of heart beats in pairs. Synonym: bigemini. Origin: bi-+ L. Geminus, twin (05 Mar 2000) |

| atrial bigeminy | Pairing of atrial beats, as when an atrial extrasystole is coupled to each sinus beat. (05 Mar 2000) |
|---|---|
| atrioventricular junctional bigeminy | Paired beats, each pair consisting of an A-V nodal extrasystole coupled to a beat of the dominant, usually sinus, rhythm. Synonym: nodal bigeminy. (05 Mar 2000) |
| ventricular bigeminy | Paired ventricular beats, the common form consisting of ventricular extrasystoles coupled to sinus beats. (05 Mar 2000) |
| reciprocal bigeminy | Paired beats, each pair consisting of an A-V nodal beat followed by a reciprocal beat. (05 Mar 2000) |
| rule of bigeminy | Rule that a ventricular premature beat will follow the beat terminating a long cycle. Sudden prolongation of the ventricular cycle, by changing the refractoriness in the conduction system, causes a peripheral region of bidirectional block to become transiently unidirectional and thus opens potential pathways for reentry to occur. (05 Mar 2000) |
| nodal bigeminy | Paired beats, each pair consisting of an A-V nodal extrasystole coupled to a beat of the dominant, usually sinus, rhythm. Synonym: nodal bigeminy. (05 Mar 2000) |
| escape-capture bigeminy | Paired beats, each couplet consisting of an escape beat followed by a conducted sinus beat. (05 Mar 2000) |
| bigeminy |
1. occurring in pairs. 2. the occurrence of a bigeminal pulse.
