dem2 Demand 2. Mostly paced. Same as Demand 1 except 20 paced beats
and 40 normal beats.
avsq Atrial-ventricular sequential. Dual pacemaker spikes—first triggers
P-wave, second triggers QRST—0.15 seconds apart.
nonc Non-capture. Asynchronous paced except every 10th beat there is no
QRST response.
nonf Non-function. Pacemaker spikes only. No QRST response.
The ATRIAL PACER and the VENTRICLE PACER can be varied independently—the
amplitude (height) from -700 mV to +700 mV and the width from 0.1 ms to 2 ms.
To set atrial pacemaker parameters:
1. Press -ATR from the PACEMAKER MENU, to reach the ATRIAL PACER
MENU, and the following display:
ATRIAL PACER
WIDTH AMP

2. To set atrial pacemaker amplitude (height) and atrial pacemaker width
parameters, press the corresponding function keys, and then follow instructions
for step menu functions. The displays follow:
atrial height: ### mv
