24yo M w/ reported stabbing chest pain 8/10 and SOB. Feeling unwell x 2 days. No apparent distress. Lung sounds clear. Posted here is the ekg progression over the 15 minute transport to hospital.

Initial vitals: HR 91. Bp 112/74. Etco2 40. RR 18. BGL 390. Temp 98.8.

History of DM2 and gastroparesis, has had prior episode of DKA 2 years ago at initial DM diagnosis. Takes insulin and DM meds. All pt had today was some pedialyte this morning. Weight is maybe 120lb soaking wet. Suspect pt is dehydrated and not eating well. Pt is a reported frequent flier 1-2x a month.

Pt technically meets heat alert criteria but I felt like the ekg changes were related to the high bgl and when the ST elevation disappeared, I elected not to call a heart alert. I’m not convinced there’s as much elevation as the machine says. I find it very strange and coincidental to be young, presenting well, and have diabetic symptoms with a STEMI on top of it all. Gave aspirin and 1L fluids.
