title: [Medtronic model 6500 temporary myocardial pacing lead: a report of clinical assessment until three weeks after cardiac surgery].
abstract: Medtronic model 6500 heart wire as a right ventricular electrode was assessed in 41 postoperative cases. R-wave amplitude, slew rate, peak-to-peak, output, current, and resistance were measured by Medtronic A-V pacing system analyser, model 5311, for three weeks after open heart surgery. These parameter changed until the 7 th postoperative day, but did not change significantly thereafter. Output and current did not exceed beyond 10 V and 20 mA respectively, where there is limitations of usually available pacemaker. No complication was encountered. These results showed that this heart wire was reliably useful even until 3 weeks after open heart surgery.
