Did anyone experience orthostatic hypotension post syrgery my bp drops from 12/75 when lying down to 107/70 when sitting to 10/7 when standing does anyone have an idea qhy this would happen and persist 6 month post operation?
orthostatic hypotension

Help Support Valve Replacement Forums:
Do you mean that your bp when sitting drops from 107/70 to 100/70 when you stand (10/7 and you'd be dead) ? If so, I don't think that is orthostatic hypotension - I believe that orthostatic hypotension is when the bp drops such that is causes a person to feel dizzy or faint - if you're expereincing that you should probably see your doctor.
When I record my bp I usually take at least three readings to get an average, and even without going from one position to another I can get very big differences between each measurement as bp changes from one minute to the next.

The Mayo Clinic has some good info: http://www.mayoclinic.org/diseases-conditions/orthostatic-hypotension/basics/definition/con-20031255. Basically, it's usually nothing to worry about, and might be caused by heart problems, like a bad valve, or medication taken for heart problems. If you're on this forum, you probably have one of those. My doctor told me that we might have to ease up on meds if my systolic pressure (the top number) gets below 90, so even 100 is not "too" low.
I'm off all heart meds and my systolic is now approaching 100 AND I'M SO PLEASED ! After surgery and for nearly months my systolic has been around 140 and my diastoic in the 80s and 90s, even 100 a few times ! Not good for it to be so high I think. I read the other day that there's no number too low - obviously if it's causing dizzyness then yes, but if not then it's better to have lower bp rather than higher bp imho. But something that worries should be addressed.

Did u try taking ur blood pressure in different positions like when standing and when lying down? My problem is that it falls to 100 when standing and my heart rate moves from 85 to 120
I'll try and do a sitting and then standing bp test sometime over the next few days. When I tried just now my bp is just too high for my comfort (135/89) - it was much lower the other day which is my normal - so once it's back to my normal I'll check it going from sitting to standing and let you know my measurements.
Here's an interesting paper: http://www.aafp.org/afp/2011/0901/p527.html
Orthostatic hypotension is defined as a decrease in systolic blood pressure of 20 mm Hg or a decrease in diastolic blood pressure of 10 mm Hg within three minutes of standing compared with blood pressure from the sitting or supine position.
A normal hemodynamic response to changes in posture requires normal function of the cardiovascular and autonomic nervous systems. Standing results in blood pooling of approximately 500 to 1,000 mL in the lower extremities and splanchnic circulation. This initiates an increase in sympathetic outflow, which increases peripheral vascular resistance, venous return, and cardiac output, thereby limiting the decrease in blood pressure.
These compensatory mechanisms result in a decrease in systolic blood pressure (5 to 10 mm Hg), an increase in diastolic blood pressure (5 to 10 mm Hg), and an increase in pulse rate (10 to 25 beats per minute). However, orthostatic hypotension may result if there is inadequate intravascular volume, autonomic nervous system dysfunction, decreased venous return, or inability to increase cardiac output in response to postural changes. Decreased cerebral perfusion produces the neurologic symptoms of orthostatic hypotension.

Hi Lebaneso, I've now taken several sitting and then standing bp readings, you'll see that sometimes the bp rises and sometimes it falls with me:
Sitting: 104/74 HR 85 - then standing: 99/74 HR 102
Sitting: 96/72 HR 82 - then standing: 110/82 HR 100
Sitting: 118/80 HR 82 - then standing: 113/81 HR 91
Sitting: 101/66 HR 88 - then standing: 82/65 HR 102
Sitting: 104/74 HR 85 - then standing: 99/74 HR 102
Sitting: 96/72 HR 82 - then standing: 110/82 HR 100
Sitting: 118/80 HR 82 - then standing: 113/81 HR 91
Sitting: 101/66 HR 88 - then standing: 82/65 HR 102
