left arm-Right arm blood pressure

Is it common to have different reading of blood pressure between the left and right arm. The right is 140/85 and the left 117/75. These are pretty constant reading taken at the same time over a week. I take topol xl after having 2 stents in October 2005. Any help appreciated.

Re: left arm-Right arm blood pressure

It may be fine to see variations occasionally but I think that is usually a consequence of additional rest time before the second reading.
Try varying the sequence of first-second...perhaps for a couple days do 4 readings at a time (4 minutes apart) and average them. Start Day one with the LEFT and Day 2 with the RIGHT.

IF you are showing a consistent and verifiable difference of over 20 points systolic and 10 points diastolic after having taken enough safeguards to rule out coincidence, you'd best lay all the data in front of your cardiologist. People with huge differences are usually those with proven vascular disease and it might indicate some large vessel (aorta) blockage or kidney involvement. Some things he may want to do is to work up comparisons between arm and leg BP's and also to use two people or testers to test both arms AT THE SAME TIME.

One doctor said that his research has shown that about 4% of his patients showed a >20 systolic difference or >10 diastolic...but it was a small sample.

It's definitely worth looking into once you have assured yourself the readings aren't flukes.

Re: left arm-Right arm blood pressure

I consistently have a 15-20 pt difference between my left and right arm.

Is your left and right arm blood pressure about the same?

Re: left arm-Right arm blood pressure


Sometimes I think the right arm is a little higher, other times I think not. If there's a difference it isn't a lot and it isn't consistent.

I guess the only way to be SURE is to take BOTH at the same time.

Re: left arm-Right arm blood pressure more questions

I usually test my BP in a pharmacy and the way the machine is set up we have to put our left arm in. So I don't know about the left arm right arm difference, but I have noticed something I would like advice on.

When I check my pressure I hate when you can feel the pulse pulsating through the cuff, I don't like the sensation so it always stresses me a bit and my BP is always high like 140 and over. The lower number is usually 70-80. But when I take it again 1 minute later, the higher number has dropped about 5 numbers and the lower number has increased. Isn't that a bit odd?

The other thing I find weird is whenever my BP is checked by a Medical professional like a a doctor or nurse, they always tell me my BP is normal. They never tell me the number but they say its normal and sometimes they say it's very good. So why is there such a difference when I check it msyelf at those machines? WHy is it always high there?
