2. Click on the patient's ECG tab.
3. Click on the Relearn button.
Solution: Check ECG signal from patient.
1. Check/adjust lead placement.
2. Check/perform skin preparation.
3. Check/replace electrodes.
4. Correct artifact source.
There are two general things that occur when the pace mode is activated for
pacemaker patients:
1. Beats that would otherwise be classified as ventricular are instead classified as V-
paced if a ventricular pacemaker event is detected.
2. Residual pacemaker energy that might otherwise appear in the ECG is removed,
and a white pacemaker enhancement spike is artificially placed in the ECG.
Pace detection is indicated visually in the ECG parameter box. When watching the
ECG waveform, pace detection is indicated by uniform, upright pacemaker
enhancement spikes in the ECG data (both displayed and graphed).
NOTE
To improve pacemaker detection, reposition the electrodes and ensure a good
skin preparation to maximize R-wave detection. Perform a relearn any time lead
positions are changed. For more information, refer to
page 6-2.
During telemetry monitoring, the pacemaker signal is acquired from lead II or on II
and V simultaneously when using the ApexPro CH transmitter. Changing the
displayed lead has no effect on pacemaker detection.
NOTE
With all leads connected, pacemaker signal acquisition occurs on lead II or on II
and V simultaneously when using the ApexPro CH transmitter. In a Leads Fail
condition, signal acquisition occurs on any available lead. When a 3-leadwire set
is used, single channel acquisition occurs on the programmed lead.
To improve pacemaker detection, reposition the electrodes and assure a good skin
preparation to maximize R-wave detection. The following is a suggested
configuration:
