Abstract
Results On implantation the mean threshold of all the leads was 1.1+/-0.8V at a mean pulse width of 0.5+/-0.7ms. The mean impedance of the leads was 673.4+/-268.1 OH. There was no difference in the implant data between unipolar and bipolar or steroid eluting and non-steroid eluting leads. There was a significantly lower pacing threshold in the steroid eluting leads at latest follow up (p=0.031). Similarly the pacing thresholds were lower in the bipolar leads when compared to the unipolar leads (p=0.026). There was no difference in impedance.
Highlights
Indications for epicardial pacemaker insertion in the adult population include; complex congenital cardiac defects, difficult venous access, tricuspid valve pathology and in patients undergoing concomitant cardiac surgical procedures
Between February 2008 and October 2012, 103 epicardial pacing wires were implanted in 70 adult patients
There was no difference in the implant data between unipolar and bipolar or steroid eluting and non-steroid eluting leads
Summary
Indications for epicardial pacemaker insertion in the adult population include; complex congenital cardiac defects, difficult venous access, tricuspid valve pathology and in patients undergoing concomitant cardiac surgical procedures. It still remains unclear as to the best type of lead used for this. Authors’ details 1Salford Royal NHS Foundation Trust, Salford, UK.
