Decreased ejection fraction after implantation
I have 46 years old and already served a month with my PM implant because a degenerative disease of AV node. Yesterday made me a gamagramma, but it turned out that there is:
1. Slight apical defect that improves in stress in relation to recent PM
2. Dilated left ventricle (VTD 139ml, VTS 71ml) with borderline systolic function, LVEF 49%
3. Important asynchronous contraction of VI with a bandwidth of 240º, standard deviation of 60º, with the last viable contractile segment located in the middle lower side segment
In an echocardiogram that they did a month before implantation, my LVEF was 72% and there was no LV dilation, I have read that a poor placement of the electrode in the RV can cause the LVEF to drop, the LV to dilate and asynchrony occurs
Has something similar happened to anyone?
