Initial Impression: Suspected ST-Elevation Myocardial Infarction (STEMI) Justification for F1 Classification: - Severe chest pain with radiation, shortness of breath, diaphoresis, nausea, and dizziness are highly suggestive of acute myocardial infarction - Time-critical condition requiring immediate intervention to minimize myocardial damage - Patient's symptoms indicate a high risk of cardiac arrest Differential Diagnoses: 1. STEMI (high probability) 2. Unstable Angina (less likely given severity of symptoms and radiation) 3. Aortic Dissection (less likely given absence of tearing pain) 4. Pulmonary Embolism (less likely given lack of pleuritic pain and sudden onset) Required Actions: - Dispatch of ground EMS with ALS capabilities - Immediate ECG acquisition and transmission for STEMI confirmation - Activation of cardiac catheterization lab at nearest PCI-capable hospital - Oxygen administration and pain management protocols initiation - Preparation for immediate transport to hospital
