Hi - a few months ago I was having heart palpitations due to anxiety and ever since I have become really obsessed with my heart (I guess I m stupid). When I get up in the morning I m always checking my pulse. What are my chances of having a heart attack one day? I think i m healthy, my BMI is 22 which also means I m not obese, I don t smoke or drink, I have a good diet including fruit every day, I have low blood pressure, I exercise moderately like twice a week and above all there is no family history of heart attacks. THANK YOU.
