Function Select - ECG - Pacemaker Menu
To access the PACEMAKER MENU:
1. Press <F1>-PACE from page 2 of the ECG MENU.
The three main pacemaker parameter selections are pace wave, atrial pacer, and
ventricle pacer, and are displayed as shown:

In the PACE WAVE MENU, the atrial-ventricular sequential waveform uses
both atrial and ventricular pacemakers. All others use the ventricular pacemaker.
The pacemaker rate is 75 BPM.
Note
The ventricular pacemaker triggers a wide QRST wave similar to LBBB
since the ventricular pacemaker is in the right ventricle.
Descriptions of the pacemaker waveform selections follow:
Selections Descriptions
nsr
Normal sinus rhythm. Provides a convenient way to return to normal
sinus rhythm.
asnc Asynchronous. At 75 BPM, continuously paced.
dem1 Demand 1. Mostly paced. A series of 40 paced beats and 20 normal
beats. Pacemaker kicks in when normal beat is 20 % late and kicks
out when normal beat comes in time for an 80 BPM rate.
