Intraoperative pacemaker electrical testing.

To determine the clinical value of intraoperative pacemaker system electrical testing, the results of 200 consecutive pacemaker procedures (95 ventricular and 6 atrial primary implantations, 88 generator replacements, and 11 system revisions) were reviewed. The rationale and technique of testing maneuvers are described, including the use of a compact pacing system analyzer wrapped and used on the sterile operating field.
