Docs often say different things thus it's a good strategy to ask not one but at least two.
If you dont have any arrythmias and you can run several miles with a little bit strong and fast heart beating its absolutely normal if you're exercising regularely. 28 years is young so you're of course having fatty streaks in the arterias but not dangerous one's.
If you dont have asthma and you want only stop the adrenaline rush from your adrenal gland I would recommend:
Corgard (nadolol) approx. 40mg a day works 24h
It does not cause b1/2 upregulation according two at least two studies. One positive thing is that it is not cardiodepressant. That means you're jogging at least the miles too with this betablocker (in contrast to propranolol which is very cardiodepressant, lipophil, upregulation by time)
Oxprenolol retard (has ISA following b1/b2 downregulation)Propranolol
Both are unselective but proven effective against catecholamines.
Isoprenaline is a beta1/beta2 agonist (works similar like adrenaline). It's used in the laboratory because adrenaline's half-life is too short.
If you want I can e-mail you some different studies about the efficacy of betablockers against catecholamines and measurements of many other parameters.
