** Non-Sustain VT A run of PVCs < the V-Tach run limit
and ventricular heart rate > the V-Tach
HR limit
x
** Vent Rhythm A dominant rhythm of adjacent Vs >
the vent rhythm limit and ventricular
heart rate < the V-Tach HR limit
x
** Run PVCs High A run of > 2 PVCs x
** Pair PVCs Two ventricular beats between two
non-ventricular beats
x
** R-on-T PVCs For HR < 100, a PVC with R-R interval
< 1/3 the average interval followed by
a compensatory pause of 1.25*(the
average R-R interval), or two such Vs
without compensatory pause occurring
within 5 minutes of each other. (When
HR > 100, 1/3 R-R interval is too short
for beat detection)
x
** Vent Bigeminy A dominant rhythm of N, V, N, V (N =
supraventricular beat, V=ventricular
beat)
x
** Vent Trigeminy A dominant rhythm of N, N, V, N, N,
V (N = supraventricular beat, V =
ventricular beat)
x
** PVCs/min High PVCs detected within a minute > the
alarm limit
xx
** Multiform PVCs Two different shaped Vs detected, each
occurring at least twice within the last
300 beats and at least once within the
last 60 beats
x
** Pause No beat detected for a period > the
pause threshold
x
** Missed Beat No beat detected for > 1.75*(the
averaged R-R interval), or no beat
detected for > one second if HR > 120
