Abstract
bradyarrhythmia due to drug intoxication (109 patients, 13.9%), symptomatic sick sinus syndrome (83 patients, 10.7%). The route of insertion was via the internal jugular vein in 100% of the cases. The duration of transvenous pacing use was 3.8 days (range, 1 to 24 days). A total of 184 patients (23.5%) required a permanent pacemaker. No deaths were seen attributable to transvenous pacemaker implantation. Other minor complications were seen in 12 patients (1.5%). Malfunction of the temporary pacing lead occurred in 14 patients (1.8%) because of electrode displacement. Conclusions: Temporary pacemakers are used in extreme bradyarrhythmias and during acute myocardial infarction. Complications are rarely seen. In 1.8% of the patients the electrode needed to be repositioned because of failure of sensing or loss of ventricular capture.
