You do not have a Heart attack
. It was Panic attack
as you weredisoriented.
What you needed was a Clonazepam
0.5mg stat and Prn.
You may as well get your ECG and which will rule out Cardic infarction
. you were not sweating. Get your Treponin !! levels and LDH & SGOT & SGPT levels.
body tinglenes can occur in panic attack and mimic a heart attack.
But if you really had an attack survival without intervention would have have been low and you could not have slept that way without sweating.
Goodluck get investigated and take some aspirin and get an opinion and follow advise ast to why you developed this attack??
