Sounds like your heart's electrical system gets over-stimulated. This could be from caffeine; too much carbohydrate in diet; encounters with chemicals, pollen, allergen, irritants, etc.
Do you have allergies or asthma? Do you smoke or are you around others who smoke? Drink coffee or tea? Eat chocolate?
Currently when running I experience no dizziness,shortness of breath,chest pains or faint feelings and I notice my pulse lingers around 120 bpm after a couple of 10 minute miles for a couple of hours.
Have you ever experienced dizziness,shortness of breath,chest pains or faint feelings?
Has anyone experienced similar physiological responses without feeling your heart beats through the usual flutters or flip-flops,etc.? Also, out of concern for this irregularity I now am cautious to the point of limiting the miles per week that I run as well as the speed I run at.
I've been dealing with Heart Failure and Persistent Atrial Fibrillation for over 25 years. My heart flips and flops and races and beats strongly and beats weakly and beats slowly and skips beats, etc., quite frequently. In fact, if my heart EVER beat normally, then I would worry!
I am 70 and I do up to 500 pushups per day, 300 weight curls per day, 12 minutes on my stepper, one hour power walk, 20 side weight lifts; and 10 minutes on my bike.
I will delay my exercises if I have any worrisome symptoms, such as dizziness,shortness of breath,chest pains or faint feelings? If I feel pretty good, I'll do my exercises regardless of my heartbeat and heart rhythm gyrations.
I am not suggesting that it would be healthy for you to do as I do. Just giving you things to think about from a different perspective.
Regards, and best of luck and health, from a fellow, but retired, runner.
