Hypochondria or Heart Problem?

IOverall, you could probably have hypochondria. I know someone who has this, They are constantly checking their heart rate to see if it is coming down and say things like my heart is coming out of my chest, i can't concentrate because my heart rate is through the roof. Irrational things... My heart comes down fast after I run consecutively for a few days. I don't actually care if its high. I know I can get it down through cardio exercise. Be aware that your thoughts could be irrational and created by your own fears probably of dying. I don't think there is such thing as not fearing death. On some level we have a fear of it no matter how slight. I don't think I fear it but then again I know probably deep within I could. It becomes irrational when you are constantly feeling there is something wrong with you when you are fine. You should trust the doctors, you are fine, high heart rate could be stress related, diet related and lack of exercise. Stop rubbing your chest or any habits to do with analysing the heart like testing or trying to listen to the heart rate. It will come down, if you take the measures to bring it down, but do not think your heart rate is abnormal, this would put your life on hold and your habits of analysing could really put your life on hold. best of luck!!
