[|Human|] I just had something hit me, I started with my heart pounding 100 miles a minute, then my head starts pounding, I couldn t breathe, and my body was burning from the inside out. This has happen to me twice in the last 3 months and you feel like you are about to die when this happens.
[|AI|]  Hello! Thank you for asking on Chat Doctor! Facing your recent complaints, it seems to be any cardiac arrhythmia (probably supraventricular tachycardia). It is necessary to perform a medical check up (physical exam, resting ECG and some blood tests) to investigate for any identifiable reasons. A cardiac ultrasound and an ambulatory ECG monitoring may be judged useful by your doctor if there are any suspicions to confirm. Hope to have been helpful. Greetings!
