Background: Temporary pacemakers (TP) allow short-term ventricular pacing but can be unstable and become ineffective during extended use. Semi-permanent pacemakers (SPP) are active fixation leads connected to an externalized pacemaker generator and may provide a more stable pacing platform. The outcomes following SPP compared with TP placement are unknown.
Methods: A retrospective analysis was performed on all patients with an SPP or TP placed at a single medical center from January, 2010 to September, 2015. Patients were included if the SPP or TP was required beyond an acute procedure. Demographics, indications, minor complications (undersensing, need for transfusion, hematoma, or diaphragmatic stimulation), major complications (loss of capture, need for repositioning, cardiac perforation, carotid puncture, induction of ventricular arrhythmia), and survival were compared.
Results: A total of 32 SPP and 114 TP were implanted during the study period and included for analysis. SPP were more often placed following lead extraction (25% versus 7%, p<0.0001). TP were placed more often for symptomatic complete heart block (68% versus 25%, p<0.0001). SPP remained implanted for significantly longer average time (197 versus 49 hours, p<0.0001). Despite this, the time spent in the ICU was no different (p=0.29). There was no difference in the number of complications with SPP and TP (25% versus 20%, p=0.48). Major complications, however, were significantly more likely with TP (14% versus 0%, p=0.023), with 11% due to failure to capture. There was no difference in survival between the two groups (p=0.66).
Conclusions: In this retrospective study, SPP provided more stable temporary pacing support with a lower rate of major complications than TP. SPP should be considered in patients requiring temporary pacing, particularly if longer-term temporary pacing is anticipated.
