10.6.2 Arrhythimia Options
Mortara algorithm package
When Mortara algorithm package is configured, your monitor has the following extended
arrhythmia analysis option.
Arrhythmia Message Description
ASYSTOLE No QRS complex within the defined time in absence of ventricular
fibrillation or chaotic signals.
VFIB Ventricular fibrillation occurs and persists for 6 seconds.
VTAC Ventricular HR is greater or equal to the defined limit and the number
of consecutive PVCs is greater than the defined value.
PNP No pace pulse within (60*1000/pace rate +90) milliseconds following a
QRS complex or a pacer pulse (for paced patient only).
PNC No QRS complex within 300 milliseconds following a pace pulse (for
paced patient only).
V RHYTHM Ventricular HR is less than the defined limit and the number of PVCs is
greater than 3.
COUPLET Pair PVCs are detected.
VT > 2 Ventricular HR is greater than or equal to the defined limit and the
number of PVCs is greater than or equal to 3 but less than the defined
limit.
BIGEMINY A dominant rhythm of N, V,N, V, N, V.
TRIGEMINY A dominant rhythm of N, N, V,N, N, V, N, N, V.
R ON T R on T is detected.
MULTIF. PVC More than two forms of PVCs are detected within the defined search
window (3 to 31).
IRR. RHYTHM Consistently irregular rhythm
MISSED BEATS No beat detected for 1.75x average R-R interval for HR <120, or No
beat for 1 second with HR >120 (non-paced patient only), or No beat
detected for more than the set pause threshold.
BRADY The HR is less than or equal to the defined bradycardia low limit.
TACHY The HR is greater than or equal to the defined tachycardia high limit.
