Hello doctor, I am a 20-year-old male and I need you to tell me if it seems like I could have a heart rhythm problem. I have a constant awareness of my heartbeat, but my pulse is always normal so my doctor attributes this to anxiety. I do not have a murmur and my doctor has always said my heart sounds fine. However, whenever I am sitting for a long time and then I stand up, I get very lightheaded. I read online that could be a sign of a heart rhythm problem. I have never passed out. I am not overweight and I do not smoke. My only symptoms are constant awareness of heartbeat especially at night and the occasional dizziness upon standing. Does this seem like SVT or a heart problem?
