there is difference in blood pressure reading taken from the right arm as compared to left arm?

Question

MY bp reading is different from the right arm as against that of the left arm

Answer 1

There is. It is because of the difference in the origin of the left brachial artery and the origin of the right one

Answer 2

OK, there can be a lot of reasons for this. We'll start with the scariest.
1. An aortic dissection at the aortic arch. Usually the BP is higher in the right arm if this is the case. The right arm is getting blood from the aorta before the damaged area, the left is getting blood from the aorta after the damaged area, creating a difference in blood pressures.
2. There may be a problem with the vessels in one arm, either from a previous injury or from vascular disease.
3. There may be a problem with the BP cuff you are using. Misaligned, misplaced, etc.
4. No 2 BPs are exactly the same, a small amount of variation is normal
5. There may be differences due to dominant vs non-dominant hand. One arm can be stronger / more muscular than the other. This can effect the measurement of BP.
Talk to your MD about the difference and any other symptoms you may be having.
Good luck

Answer 3

Yes, that is true. I have been told you should try to always have your bp taken from the same arm to ensure they will be more accurate. I had a nurse question my blood pressure once. The doctor told her to make sure she was taking it from the same arm each time.

Answer 4

It is possible because the heart is on the left side of the body and all the vessel (arterial and venous) have a little pressure difference between the left side and right side. But your difference is high (from my point of view).

Answer 5

There should not be a signficant difference unless there is a circulation problem in one of your arms.

There can be natural variation from minute to minute of a few points, but if one arm is consistently more than a few points lower than the other, then that arm has a problem with the circulation.
