arrhythmia
Pacer not paced
No pace pulse detected for (60*1000/pace rate +90) milliseconds
following a QRS complex or a pacer pulse (for paced patients only).
Pacer not capture

(for paced patients only).
Multif. PVC
More than 2 PVCs of different forms occur in the predefined search
window (3-31).
Couplet

Run PVCs
Ventricular HR is greater than or equal to the preset threshold and the
number of PVCs is greater than or equal to 3 but less than the preset
threshold.
Vent. Rhythm
Ventricular HR is less than the preset threshold and the number of PVCs
is greater than or equal to 3.
Bigeminy
