Your heart rate
is considered as normal.
Heart rate between 60-100 bpm is considered as normal.
There may be increase in heart rate in any sort of anxiety
as you were conscious regarding your heart rate.
Still you should go for electrocardiogram (ECG) to rule out any irregularity in heart rate and for better clarification.
Avoid taking excessive tea, coffee, chocolates as these edibles may cause rise in heart rate.
