A047 Transvenous Temporary Cardiac Pacing at Middlemore Hospital Over the Last 6 Years. A Retrospective Audit

Abstract

Transvenous temporary cardiac pacing (TV-TP) is widely used to treat life-threatening arrhythmias. This audit evaluated the indications and complications of all patients that received TV-TP at Middlemore Hospital in the last 6 years. A retrospective audit from 2014-2020 of all patients treated with TV-TP in the catheterisation lab or with the portable II machine at Middlemore Hospital were included. 70 patients were included, of which 43(61%) were male. The average age was 71(41-93). 30(43%) were NZ European, 23(33%) were Pacific Island or Māori. The average BMI was 29kg/m2 (range 19-51). Complete heart block was the most common indication (36%). Myocardial infarction was seen in 10(14%) cases. 20(29%) were done prophylactically prior to planned procedures. Right femoral vein was the most common access point 55(79%). 42(60%) cases were done in the catheterisation lab, 17(24%) cases in the coronary care. The median time from decision to implantation was approximately 1.5 hours. There was a lack of complete documentation in 7 cases. The average duration of insertion was 2 days (54mins – 5 days). 45% required a permanent pacemaker, implanted on average 1.2 days later. One patient had loss of capture due to lead displacement. 6 patients died within 30 days of TV-TP due to the underlying condition. An Interventional or EP Cardiologist was involved in 53(76%) cases. Patients requiring TV-TP is done in a safe and timely manner by both interventional and non-interventional cardiologists regardless of location in the hospital. Indications and complications are in line with other studies.
