The last week ive been having heart palpitations back to back theyre so uncomfortable and just now for about two hours ago ive counted 30+ palpitations back to back!! Within a few minutes or within 20. My heart rate is jumping between 90 to 120. Ive been to the hospital for chest pain and everytime they check my heart they dismiss me and say im fine. But this is probably the worst ive had palpitations!! Im scared my hearts gonna stop suddenly idk if i should go to the ER again or not..
