1 week since my CRT-P install. Had my dual lead pacemaker replaced as EP feels it's causing pacemaker induced cardiomyopathy (low 40's EF with some dilation of both ventricles). I was RV pacing about 90% of the time with the dual lead PM. My QRS under RV pacing was real wide above 150 ms ie: ventricle dyssyncrony. The good news so far is that I don't have any symptoms from the cardiomyopathy except for maybe a little abdomen water weight and I still have good exercise tolerance so I feel there's been no significant damage so far.
Anybody out there had this type of cardiomyopathy? Did CRT-P help you get back to near normal and how long did it take for improvements? EP said average improvement from the CRT should be a 10 pt bump in EF ie: say 40% to 50%.
ps: I've heard that some can see good results in a few months.
