Bigeminy is a cardiac arrhythmia in which there is a single ectopic beat, or irregular heartbeat, following each regular heartbeat. Most often this is due to ectopic beats occurring so frequently that there is one after each sinus beat, or normal heartbeat. The two beats are figuratively similar to two twins (hence bi- + gemini). For example, in ventricular bigeminy, a sinus beat is shortly followed … WebThe presence of occasional coupled beats; Long pauses in an otherwise regular rhythm; A continuous and totally unpredictable irregularity; Slow but strong and regular beats; Answers and Rationales.

The frequency of premature beats is increased in a wide range of … WebA ventricular beat follows each sinus beat and the coupling interval between the ventricular beat and the previous sinus QRS complex is constant (ie, fixed coupling interval). As shown in Figure 4, a ventricular trigeminy is present when two sinus beats are followed by the VPB. Thus, every third beat is a VPB. patrick purcell pa
