How to tell difference between anxiety attack and heart attack?

Bro, during exams my chest gets super tight and my heart starts racing like crazy, which is mostly just severe anxiety. But I've read that a real heart attack involves radiating pain down your left arm or jaw, and breathing becomes extremely difficult. It's super scary, so definitely see a doctor if it feels weird.

Please do not try to self-diagnose when it comes to chest pain. Even if you think it is just stress or anxiety, a heart condition is too dangerous to ignore. Go to the nearest clinic or emergency room immediately to get an ECG done for your own safety.

I literally overthink every single heartbeat and constantly worry about this. They say anxiety attacks usually peak within 10 minutes and slowly fade, whereas heart attack symptoms don't go away and keep getting worse. If you are feeling this right now, please stay safe and call a doctor to be absolutely sure.

I have dealt with panic episodes for years now. With anxiety, the chest tightness is usually accompanied by hyperventilation and a feeling of impending doom, but it gets better with deep breathing. A heart attack feels like a heavy, squeezing pressure in the center of the chest, often with sweating and nausea, which is a medical emergency. Always get a professional checkup to rule out cardiac issues.
