Was just wondering about something, and hopfully someone here may know about. I'm on imipramine, my normal blood pressure is 140/99 with a pulse of around 85bpm. So anyway now that im on imipramine my laying pressure is 160/100 but with a pulse of 52bpm. Now when i stand up my pressure drops to around 85/45 with a pulse of 132bpm. Now what i'm wondering is... when layng down is the strain on my heart going to be somewhat equal to the strain on it when standing because when standing it is beating faster but with less pressure where as laying down the pressure is high but is pumping less often.

Your heart rate speeds up when you stand in order to compensate for the drop in arterial blood pressure. The system is designed to keep cardiac output consistent to the tissues.
Your heart rate is almost always going to be more when you are standing up.
Imipramine is notorious for inducing orthostatic hypotension. Have you almost fainted when standing?
I am worried though, that your resting systolic BP is 160, the diastolic is also a little high.
Seldom.

> Seldom.I almost fainted once, so i've lowered the dose from 150mg to 100. An yeah my BP is high but if i take my BP medication which is a beta blocker it makes the hypotension worse.
Also it's not just when standing like in the usual orthostatic hypotension, the BP drop and pulse rise stay like it for as long as i'm up.So i'm hoping the high BP/low pule and high BP low pulse sort of offset each other so the strain isn't greater on my heart in either situation.
