Arrhythmia Relearning 6 ECG, Arrhythmia, and ST Monitoring

Ectopic Status Messages

The label B or E indicates basic (B) or enhanced (E) arrhythmia capability.

Ectopic Status Message	Explanation	B or E
(No message displayed)	No ectopic activity within the last minute
RUN PVCs	More than 2 consecutive PVCs within the last minute	E
PAIR PVCs	Pair PVCs within the last minute	E
PACER NOT CAPT	Pause with pace pulse (paced patient only) within the last minute	B, E
PACER NOT PACE	Pause without pace pulse (paced patient only) within the last minute	B, E
PAUSE	No beat detected for 1.75 x average R-R interval for HR <120, or	E
	No beat for 1 second with HR >120 (non-paced patient only), or
	No beat detected for more than the set pause threshold.
R-ON-T PVCs	R-ON-T detected within the last minute	E
MULTIFORM PVCs	Multiform PVCs detected within the last minute	E
FREQUENT SVPBs	SVPB count within last minute is greater than 5	E
SVPBs	1-5 SVPBs in the last minute with a sinus rhythm and no Vs	E
SV BEATS	SV count within last minute and rhythm status is PACED	B, E
PACED BEATS	Paced beat count within last minute and rhythm status is NOT	B, E
	PACED

Arrhythmia Relearning

During a learning phase:

•Alarm timeout periods are cleared

•Stored arrhythmia templates are cleared

•Asystole, Vfib, and HR alarms (when there are enough beats to compute the HR) are active. No other alarms are active.

Initiating Arrhythmia Relearning Manually

1To initiate relearning manually, in the Setup Arrhythmia menu, select Relearn Arrhy.

–While the monitor is learning, the delayed arrhythmia wave displays the beat label L and the rhythm status message LEARNING ECG.

–Next, the monitor determines the dominant rhythm. The beats are labeled N, and the rhythm status message changes to LEARNING RHYTHM.

2After relearning is complete, you should check the delayed arrhythmia wave to ensure that the algorithm is labeling the beats correctly.

3If beats are still not classified correctly, check that the ECG is optimized for arrhythmia monitoring. You may need to select a different lead or change the electrodes or electrode positions if there is excessive noise, unstable voltage, low amplitude, or large P- or T-waves.
