Your symptoms are interesting to me, I will have to take my B/P after a long cycle to see if mine lowers, if this if the case then we will have to constantly exercise! My blood pressure peaked at 220/111, then dropped to around 160, after being diagnosed with three strikes, my B/P went higher and I was getting pretty ill, stopped all my meds, took up cycling, went gluten free and do stress meditation, my morning B/P is 120/70 night max is 150/85. I am 56 by the way.
what I find interesting is you say you don't take much medicine and your B/P was 210/110, that is very dangerous B/P but is it wise to take meds when your other B/P is 120??? Good luck
This is a patient community; no medical experts answering questions here except randomly, I'm afraid.
A very common mistake is the belief that heart rate and blood pressure are proportional. At certain times, like during exercise, they are, yes. Otherwise, high blood pressure is often associated with a slow heart rate, If your arteries are constricting (in response to stress hormones), the "built in" blood pressure monitor in your body (which is located in the aortic arch and carotid arteries) are sending signals to the heart to slow down heart rate in an attempt to reduce blood pressure.
This happens especially when taking medications that prevent blood vessel dilation in response to adrenaline (like propranolol). A not uncommon case: people taking propranolol go to a dentist, get an injection of local anestethics containing adrenaline, and get a heart rate of 40 with blood pressure 200/110.
If you on occations get a blood pressure of 210/110 without any obvious cause, you should consider ruling out conditions inappropriately increasing your stress hormones. A blood pressure of 210/110 is dangerous and should not be ignored.
The fact that your blood pressure drops (and hence heart rate increases) after exercise is caused by dilation of blood vessels during and after exercise, and is normal and common. It follows the same (or rather reversed) mechanism as described above. Your pressure sensors notice that your blood pressure is low and speeds up the heart to compensate.
