Cardiologist,  's  Response
Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

I would explain that your symptoms could be related to a panic attack or anxiety. A cardiac arrhythmia can not be excluded either. For this reason, I recommend consulting with your attending physician for a physical exam and some tests:

- a resting ECG and a cardiac ultrasound
- an ambulatory 24-48 hours ECG monitoring for possible cardiac arrhythmia
- blood electrolytes for any possible imbalances
- complete blood count for anemia
- thyroid hormone levels for possible imbalances.

You should discuss with your doctor on the above tests. If all the above tests result normal, you should consider anxiety as the main cause of your complaints.

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

General Surgeon,  Dr. Shinas Hussain's  Response
Hello,

Heart beats faster during heavy physical activities and it is a normal physiological change and nothing to worry about it. You can take an ECG to rule out any abnormal rhythm or irregularities for reassurance. If symptoms persist, better to consult a cardiologist and get evaluated.

Hope I have answered your query.
