Observe the pacing stimulus marker on the display or stripchart ( ) and verify that it is
well-positioned in diastole.
4 Set Pacer Output
Increase PACER OUTOUT until stimulation is effective (capture); the output mA value is
displayed. The pacer output increments and decrements by a value of 2 mA on the display
when the knob is turned.
Note: When the unit is switched out of PACER mode into Manual mode and then switched
back to PACER mode, within 10 minutes the pacer settings remain unchanged.
If the unit is turned off for more than 10 seconds, the pacer’s power up default settings are
restored.
5 Determine Capture
It is important to recognize when pacing stimulation has produced a ventricular response
(capture). Determination of capture must be assessed both electrically and mechanically in
order to ensure appropriate circulatory support of the patient.
Electrical capture is determined by the presence of a widened QRS complex, the loss of any
underlying intrinsic rhythm, and the appearance of an extended, and sometimes enlarged,
T-wave.
Ventricular response is normally characterized by suppression of the intrinsic QRS complex.
WARNING! Determination of electrical capture should only be performed by viewing the ECG trace
on the R Series display with its ECG connection directly attached to the patient. Use of
other ECG monitoring devices might provide misleading information due to the
presence of pacer artifacts.
Mechanical capture is assessed by palpation of the peripheral pulse.
