Hi doctor! I am 27 years old this year. At times of vigorous exercise (especially when playing football with a lot of force) or times of stress and anxiety, my heart beats abnormally, this time my heart beats 3.4 times faster than normal. rapid deterioration, dizziness, lightheadedness can cause fainting.

I have a phenomenon of avoiding palpitations, feeling both in the neck and head area, especially when lying down, making it difficult to sleep. Want to know what causes palpitations, palpitations or palpitations?
