Thanks for posting your query.
Your description suggest you are having atrial fibrillation
or other cardiac arrhythmia
. In such conditions heart beats fast and irregular, if not treated promptly then it nay lead to serious complications. You are at more risk of arrhythmias if you have previous Heart Disease
. Avoid any physical or emotional stress
. Immediately visit cardiologist and perform ECG and get your treatment.
Hope it helps.
