Dude, if you’re having heart palpations, go to fucking urgent care. That shit can be lethal. Atrial fibrillation? Atrial flutter? They can cause blood clots which can cause stroke. Urgent care will know what to do, even if that’s just calling a cardiologist elsewhere to look at your EKG or even stuffing you in an ambulance and driving you to an ER.
Don’t want to take medical advice from a rando on the internet? (You shouldn’t!) Then call your goddamned nurse line. They will sort you out and tell you exactly where to go.
Good luck.
