Thanks for writing to us.
During a heavy exercise like running having a heart rate
of 180 is on a higher side. Since you are obese
and have a family history of heart disease
it is best to get yourself examined and investigated for any heart disease. In most of the cases such a raised heart rate comes back to normal in 10-15 minutes after exercise.
I hope this information has been both informative and helpful for you.
