Eh, Basic question... Does the pain radiate anywhere? What does V4R show? Posterior V7,V8,V9 show any depression, Elevation? LBBB new for this PT?, ACS maybe, With Timeline, Transmural Infarct maybe, Myocarditis... Maybe. Cardiac packet labs. CPk-MB^, Troponin^, BUN/Creatine^, Potassium^, WBC^? Syncopal episodes? Febrile? Pupils equal/reactive? H/A? Tinnitus? Blurred vision? Paresthesia? Any HX of AMS in recent hours?
I disagree with FL_Medic on Paramedics interpreting 12 Leads. If you, Or your Medics have issues with 12 Leads in your area, Then maybe y'all should reevaluate your curriculum. Why would you even consider not doing a 12 Lead with a 3,4,5 lead showing ectopy? ECG Interpretation in the field is huge in our area with our Medical Directors and receiving facilities. And yes... I said diagnose and treat for the people about to jump all over that. Maybe we just have good training, And know what were doing? Don't mean to sound arrogant.
