BIGEMINY
Occurs when two or more bigeminal cycles (a ventricular beat followed by a non-ventricular
beat) are detected.
BRADY
Bradycardia is the average of the most recent eight R-to-R intervals at a heart rate less
than the set low heart rate limit.
The Brady limit matches the low heart rate limit. If the low heart rate limit is changed, the Brady
limit changes.
COUPLET
Occurs when two ventricular beats are detected and have non-ventricular beats before and
after the couplet. The coupling interval must be less than 600 milliseconds.
IRREGULAR
Occurs when six consecutive normal R-to-R intervals vary by 100 milliseconds or more.
PAUSE
Occurs when the interval between two consecutive beats exceeds three seconds.
PVC
Isolated premature ventricular complexes occur when a premature ventricular beat is
Detected and has non-ventricular beats before and after.
R ON T
Occurs when a ventricular complex is detected within the repolarization period of a
Non-ventricular beat.
TACHY
Tachycardia is four R-to-R intervals at a heart rate greater than the set high heart rate limit.
The Tachy limit matches the high heart rate limit. If the high heart rate limit is changed, the
Tachy limit changes.
