I am a 22 year old male, 6'4 220lbs. I have had anxiety and panic attacks since a very young age. For the past 6 months, I have become obsessed with my heart and believing that I have a heart condition. Basically what I am feeling is an occasional heavy feeling in my chest, probably around 150-200 PVC's a day, and a slow heart rate of around 44-52 at rest. I also sometimes experience mild shortness of breath as well as dizziness. I also tested low for potassium (3.2) on two seperate occasions and have since started a supplement. I wore a 24 HR holter moniter a few months ago and my doctor said everything was all good and my heart just beats slow because I am young and healthy. My heart also seems to beat a little un-evenly at times. My HR responds regularly with excersise. I guess my question is, with not much heart family history and my age, would it be unlikley for me to have a heart condition? Also, could my constant worrying and obsessing over my heart be causing the PVC's? Any responses are greatly appreciated.
