I was aware of my heart beat in my arms,back, neck and stomach I checked my heart rate and it was fine Ive never felt this scared I felt like I was dying finally I calm down and fell asleep The next day I felt better most of those symptoms were gone but I was still aware of my heart beat and I felt tired and felt dizzy at one point of the day all I kept thinking about dying it was terrible On Sunday I felt even better no more dizziness but again I was aware of my heart beat and had a hard time falling asleep Anyways its been 5 days and ive gotten better but I still feel something is wrong I hate being aware of my heartbeat ,i did some search and found It might be anxiety but I also found other scary diseases just thinking about heart problems scares me im only18 and Its hard to believe its anxiety because ive only had one panic attack my whole life and thats a year ago but I also never had any heart problems or complication or High blood pressure or low I play Soccer and all of this is scaring me because Im scared to do anything that will get my heart racing , I feel fine now but I still keep thinking something is wrong also I feel at school too I will get myself checked soon this week but for now I need help on getting an idea of what this could be

Hello,

At 18 its unlikely that you have a major problem. Simple instances like lack of sleep, hunger, small physical or emotional stressors can precipitate such events. Furthur evaluation is to be considered if it repeats. HB to rule Low Hemoglobin and TSH for thyroid should be considered as blood test.

For heart EKG to see the rhythm particularly during the episode and latter 2 D echo cardiography to particularly rule out MVP, a common variant which has typically the symptoms you describe.

Keep yourself hydrated. Get good sleep. No coffee, chocolates, alcohol for the time being. Anything that excites the heart should be decreased for the time being.

Watch for GERD, stomach acid causing pain at the back side of your tongue with pungent sour hiccups may also cause the symposium you describe.

Hope I have answered your question. Let me know if I can assist you further.

Regards,
Dr. Priyank Mody , Cardiologist
