1. A pain which comes on exertion/running/ using stairs/emotional stress and relieves at rest can be anginal (heart related) pain. A pain not coming on exercise/running/carrying weights but increasing on pressing locally, which lasts for less than a minute is not likely to be anginal.
2. Whenever There is a high heart rate
(like~113 beats/min), we tend to look for a stimulus which can cause this like anxiety
, coffee, fever, stress, tea, smoking
, thyroid disorder
, any infection/ systemic illness, excessive alcohol intake, anemia
and deal accordingly. If you have any trouble because of this, you should see your GP.
Overall, whatever details you have provided, i would advise you to see your doctor and proceed as per his/her advise.
