Just curious..for the most part my heart rate is about 72 sometimes gets down to 63 at night.After I eat It goes up to about 85 for about an hour then drops to 77 and then finally to around 72.I don't seem to have breathing problems and dont get dizzy or lightheaded.I am tired alot but think that I sleep too much .I can't usually get to sleep till 5am and then sleep till about three..in the afternoon.Or could the tiredness be from some type of heart problem?. I do have a slight heart murmur and can hear my pulse in my ear and the murmur which is very disturbing but for the most part my pulse seems pretty normal.I have occassional missed beats and sometimes a little stabbing pain in my upper chest nearer to the bottom of my neck than inbetween my chest ..but it doesn't last too long...When i get around and do things I don't seem to feel bad or out of breath,but do feel tired .I was told there is really nothing wrong with my heart that she could determine but for some reason I have gotten in my mind that my heart is bad.When I was told I had a murmur I didn't know I had one and the doctor say it really wasn't worth noteing,but the fact that I could hear it in my ear first before I went to her...actually that being the real reason I was there was hearing it in my ears...it really bothered me when she told me matter of factly that I had a slight murmur..Now I worry all of the time and for some reason have in my mind that I cannot do the things I used to do.I force myself to even go to town to get food and supplies..I make myself do the laundry and things around the house but I don't stand up and exercise like I used to.I used to walk in the yard for 30 to 40 minutes a day...but now find myself copping out due to worry...So can you have high blood pressure with regular pulse and also have heart issues and don't know it ? Please advise..worried...
