8.8 About Arrhythmia Monitoring
Arrhythmia analysis provides information about the patient's cardiac parameters like heart rate, PVC rate, and rhythm.
WARNING
 Arrhythmia analysis program is intended to detect ventricular arrhythmias and atrial fibrillation. It is not
designed to detect all the atrial or supraventricular arrhythmias. It may incorrectly identify the presence or
absence of an arrhythmia. Therefore, a physician must analyze the arrhythmia information with other
clinical findings.
 The arrhythmia detection is not intended for neonatal patients.
 Heart-rate reading may be affected by cardiac arrhythmias. Do not rely entirely on rate meter alarms when
monitoring patients with arrhythmias. Always keep these patients under close surveillance.
 Atrial fibrillation (Afib) detection function is not intended for pediatric and neonatal patients.
8.8.1 Understanding the Arrhythmia Events
Mortara ECG algorithm
Arrhythmia Message Description Category
Asystole No QRS complex detected within the set time threshold (in absence of
ventricular fibrillation or chaotic signals).
Lethal
arrhythmia
Vfib Ventricular fibrillation occurs and persists for 6 seconds.
Vtac Ventricular HR is greater or equal to the preset threshold and the number of
consecutive PVCs is greater than the preset threshold.
PVCs PVCs/min exceeds high limit Nonlethal
arrhythmia
Pacer Not Pacing 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 No QRS complex detected for 300 milliseconds following a pace pulse (for paced
patients only).
Multif. PVC More than 2 PVCs of different forms occur in the predefined search window
(3-31).
Couplet Paired PVCs are detected.
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 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.
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 (for non-paced patients only), or
No beat detected for more than the set pause threshold.
