WebJan 5, 2024 · In the case of a programmed coupled pacing protocol, the authors set a standard pacing protocol choosing a drive of 8 beats as an S1 interval of 600, 500, and then 400 ms, coupled with a first extrastimulus, called S2, that is conventionally at least 60 ms higher than the documented Wenckebach interval (Fig. 2.1). Normally, the authors start ... 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).
