Thanks for writing to us.
Sedentary life style is the most common cause for rapid rise of heart rate
following initiation of exercise. Other causes may be anemia
, heart disease
, lung disease or any significant systemic illness can cause this.
I would like you to be seen by your general physician first, as many of these conditions can be ruled out by simple examination. Thereafter, if required, you may take a stress test
under physician supervision to ascertain your exercise capacity and reasons for your symptoms.
Hope this helps.
