Can physical activity, stress be actually detrimental to your heart?

Heart Problems (20 y/o, male)?

• For the past 6 months or so my heart had been beating quite hard and forceful the majority of the time. I was able to constantly see my stomach pulsating and feel my heart beat and I figured that this must be from stress and anxiety. I got it checked out and when the doctor took my blood pressure, it was pretty high. I sat in a room for 5 minutes to get blood pressure readings and my blood pressure dropped quite a bit by the end of 5 minutes. I had an EKG done and I haven't gotten a call so I assume everything was fine? Recently, my heart hasn't really been pounding that much but it still comes and goes and I thought maybe I have been dealing with stress better. I have noticed, though, that my heart rate is quite fast while standing up and is probably 100+ bpm constant while on my feet (especially noticeable in the shower). But when I am laying down before going to bed, as I am currently, my heart rate gets to between 45-60 and I can barely see/feel my pulse. I am not an athlete as I get very little exercise. However, I am not really overweight (180lbs) probably due to my metabolism and bad eating habits... Sometimes (only has started recently) before bed I get nauseous or what feels like an empty stomach. A week ago, at like midnight I felt like I had an empty stomach and I hadn't eaten much during the day so I stood up to get something to eat and nearly passed out. I'm not sure if it was due to lack of food or low heart rate (bradycardia). Here's a list of my symptoms: - Very variable heart rate & pressure - Pounding heart (more forceful when anxious, nervous, stressed or during physical activity) - Light pulse and slow heart rate when laying down before bed (only noticed it a few weeks ago) - Feeling faint or dizzy (been slightly dizzy for past ~6 months really) - Nausea/empty stomach feeling before bed (Only experienced this a few times, recently) - Slight shortness of breath (not really anymore, it used to be worse a few months ago) - Slight chest pains when doing some physical exercise The symptoms don't all happen at once, they all come and go such as right now, I'm only experiencing a low heart rate and pulse (I'm in bed) and slight nausea. Please don't reply with "GO TO EMERGENCY NOW" like I see in every post about any symptoms on the internet. It's been going on for a long time. Thanks.

• Answer:

  So whats your question? you obviously know somethings wrong with yourself so go see a doctor. if you got an EKG done ask to see the results even if you didnt get a call. sometimes doctors forget to call or your pappers get lost in the middle of things. I had the same problems as you a couple months ago. Same exact symptoms besides the chest pains when exercising. I started playing basketball for 30 minutes every day and i feel great now. However i dont know if your over weight or dont eat healthy. you said your 180 lbs but how tall are you? if your 180 and 6 foot your okay if your 180 and 5'5 you got a problem. Anyways i recommend eating healthier and atleast getting 30 minutes of mild exercise a day.
