Drop in EF after pacemaker replacement?
After 8 years of a functioning Boston Scientific N161 CRT-D, which had significantly improved my heart function, it was necessary to replace it.
New device: G151 CRT-D.
Just prior to replacement, my EF was 65. Shortly after replacement my EF was 48, with symptoms of fatigue and shortness of breath.
My electrophysiologist even agreed that seemed more than coincidence; however, he could not find anything wrong with the new device or its leads.
Anyone have siminlar experiences?
Really frustrated because it has really affected my quality of life.
