Making My Doctor Happy

I'm a bit skeptical about the improvement being entirely due to the exercise this quickly.

Are you taking the BP medication? The change in heart parameters might be the result of the medication, so if you have been taking it, don't stop. (Even so, you may not need it later as your health improves via exercise and diet. No guarantees though).

There's also a thing called "white coat hypertension", where people have mild anxiety in the doctors office that gives them a bad blood pressure and heart rate while at the doctors office that they don't have when they are out and about. That might be contributing and of course has a near-instant turn-around once you have left the doctors office.

There are a few transient things (anxiety, unrecognized minor illness/virus/bacteria) that can give you bad parameters that resolve over only a few days. One of these is baseline stress causing increased autonomic tone--if what you are observing really is the result of exercise, it's probably because the exercise is burning off some stress you may not be aware you are carrying.

Just for everyone's knowledge base--recreational drugs like viagra and its siblings are actually blood pressure medications so make sure if you are taking other blood pressure medications that you verify with your doc(s) that you are not going to get a dangerous interaction between them. If they crash your blood pressure too low you can pass out and possibly even suffer anoxic brain damage and/or blindness (because the BP is so low that not enough blood is supplied to the nerve cells of the brain and/or retina).

I guess mostly I'm worried that you don't declare yourself 'cured' and stop any medications you may have started without first consulting your doc.
