Thanks for writing in.
The complaints that you are describing can be due to various reasons. It can be due to arrhythmia
or an abnormal rhythm in the heart; excessive anxiety
or simply dehydration
. So I would suggest you get an ECG done as soon as possible, drink plenty of water and practice some deep breathing/yoga to get rid of stress
. You need an evaluation as soon as possible as sometimes these arrhythmias can be life threatening as well.
