Pacemaker to CRT-P Upgrade
I'll be getting an upgrade from a std dual lead pacemaker to a CRT-P in less than 2 weeks. EP believes my wide QRS (ventricle dyssyncrony) is causing a lowered ejection fraction. I have had 2 pacemakers in the same submucular pocket so this would be the 3rd device (I assume a larger one at that) in the same pocket. Aesthetically, previous EP did a great job with submuscular implant as there was no buldge at all after swelling went away and PM seated in pocket.
Couple of questions:
1. How much bigger is CRT-P than dual lead pm and are pocket revisions typically required?
2. A previous EP said pocket could be used many times assuming no infection or other complication. Has that been your experience?
