** HR Low Heart rate < the low HR limit x x
(see note)

(see note)
** Non-Sustain VT A run of consecutive beats labeled as V
with run length < the V-Tach Run
Limit and ventricular HR > the V-Tach
HR limit
x
** Vent Rhythm A run of consecutive beats labeled as V
with run length > the Vent rhythm limit
and ventricular HR ≤ the V-Tach HR
limit
x
** Run PVCs High A run of > 2 consecutive beats labeled
as V with run length < Vent rhythm
run limit and ventricular HR ≤ V-Tach
HR limit
x
** Pair PVCs Two ventricular beats labeled as V
between two beats not labeled as V
x
** R-on-T PVCs For HR < 100, a beat labeled as V with
R-R interval < 1/3 of the average R-R
interval followed by a compensatory
pause > 1.25 times the average R-R
interval or 2 such beats labeled as V
without a compensatory pause
occurring within 5 minutes of each
other (Note: When HR > 100, 1/3 of
the R-R interval is too short for
detection)
x
** Vent Bigeminy A dominant rhythm of beats labeled as
N, V, N, V, N
x
** Vent Trigeminy A dominant rhythm of beats labeled as
N, N, V, N, N, V, N, N
x
** PVCs/min High Within 1 minute, the number of beats
labeled as V > the PVCs/min limit
xx
** Multiform PVCs The occurrence of two differently
shaped beats labeled as V within the last
60 beats and each occurring at least
twice within the last 300 beats
x
** Pause No beat detected for a period > the
pause alarm threshold (1.5 to 2.5
seconds)
x
** Missed Beat No beat detected for a period > 1.75
times the average R-R interval for HR
< 120, or no beat detected for > 1
second with HR > 120 (Paced mode
off)
