The following table describes available beat classifications:
Arrhythmia Event and Beat Classification
ECG ASYSTOLE
5 seconds pass without the detection of valid QRS complex.
VFIB ARRHYTHMIA
Ventricular Fibrillation: The monitor identifies a sinusoidal
waveform with fibrillation characteristics.
( Certain ventricular
tachycardias have sinusoidal waveforms closely resembling those
of ventricular fibrillation. Because of the similarity of these
waveforms, the monitor may classify such types of ventricular
tachycardia as ventricular fibrillation
. )
VTAC ARRHYTHMIA
Ventricular Tachycardia: N or more PVC’s are detected in a time
interval T= (60*(N-1))/R, where N is defined as the VTAC count
and R is defined as the VTAC rate.
RUN ARRHYTHMIA
Ventricular Run: Series of 3 to N-1 consecutive PVCs with a beat
to beat rate
≥ the VTAC rate.
AIVR ARRHYTHMIA
Accelerated Idioventricular Rhythm: Series of 3 or more PVCs
with a beat rate less than the VTAC rate.
BIGEMINY ARRHYTHMIA
Ventricular Bigeminy: Sequence of beats with the pattern :
normal, PVC, normal, PVC, normal, PVC
TRIGEMINYARRHYTHMIA
Ventricular Trigeminy: Sequence of beats with the pattern :
normal, normal, PVC, normal, normal, PVC
COUPLET ARRHYTHMIA
Ventricular Couplet: Sequence of beats with the pattern :
normal, PVC, PVC, normal, PVC, PVC
TACHY ARRHYTHMIA
Sinus Tachycardia: HR ≥ TACHY rate setting. A PVC or other
abnormal beat breaks the analysis sequence and restarts analysis.
BRADY ARRHYTHMIA
Sinus Bradycardia: HR ≤ BRADY rate setting. A PVC or other
abnormal beat breaks the analysis sequence and restarts analysis.
AFIB ARRHYTHMIA
Atrial Fibrillation: Formation of QRS complexes in irregular
intervals
PAUS ARRHYTHMIA Actual R-R interval more than 2.1 times of the average R-R
interval.
FREQUENT PVCs More than N (event count set in the ARR SETUP WINDOW)
PVC per minute.
Premature Ventricular Contraction (PVC) is ectopic impulse originating from ventricles, before
the normal electrical activation sequence of the heart has occurred.
The PVC value is shown in ECG parameter window and updated every 5 seconds.
When ARR analysis is enabled, current PVC values are trended every 20 seconds and can be
reviewed on the TREND window.
