Sitting and standing bp difference
I am 65 years old female. I got my Medtronic CRT-P implant 2 months back. Since the past couple of days I feel a fainting sensation in my head on changing my postures. I consulted my doctor and he adviced for a medicine in case I feel like fainting and also to record my sitting and standing blood pressure levels. So, I did the same and got the following readings, Sitting BP (135/73 pulse - 75) and Standing BP (119/56 pulse - 82). Is the fall in blood pressure normal on standing? Does it happen with anyone else too?
I appreciate your inputs in advance
