CRT-P CRT-D Reaction Time
Had a CRT-P installed for cardiomyopathy on 3/1/19 of this year. EP thinks it was due to RV pacing from my dual chamber pacemaker causing dyssyncrony between RV and LV. I have a very wide QRS > 150 ms and a native LBBB. Recent echocardiogram 5.5 months post install doesn't show any improvment; even a slight drop in EF from 39 to 36%. I also can tell I've picked up a little water weight. I've heard of late responders to this therapy (> 1 year) but also know most see positive results within a few months if they're going to see them at all.
1. How long did it take for your CRT to increase EF and improve symptoms?
2. My EP isn't even considering any reprogramming/adjustments of CRT; he's just sending me to a heart failure specialists. Is that normal as I thought there were many ways the devices could be adjusted that might be beneficial?
