Brief Answer:
EKG/ECG recommended, but I feel all is fine sir
Detailed Answer:
Hello sir and welcome.
Thank you for writing to us.
I can understand your cause for concern, and often individuals diagnosed to have
anxiety report frequent changes with their heart beat/rhythm and on investigation, all is found to be normal.
What I would suggest is, the next time you experience this slow or soft heart beat, try reporting to a clinic/hospital or a doctor at the earliest and request for an EKG/ECG immediately, which would record your heart beat and rhythm, and would be able to predict the health of your heart. Just request for an experienced doctor to interpret the result for you, to make sure all is well.
But, in my opinion there should be nothing wrong with you sir. Please do not
stress over this, you are too young to be worrying about all this, and your heart is too young to be faced with disease. Enjoy life to the fullest, there is a lot of time to worry later on in life, worries only prevent you from doing that.
I hope you find my response both helpful and informative. Please feel free to write back to me for any further clarifications, I would be more than happy to help you.
Best wishes and live life to the fullest sir!!!
