STEMI Recognition
Definition
ST elevation in 2+ contiguous leads indicating acute myocardial infarction requiring emergent reperfusion therapy.
Key Values & Ranges
Key values and ranges relevant to stemi recognition in prehospital care:
| Parameter | Adult | Pediatric |
|---|---|---|
| temperature | 97.8-99.1 F (36.5-37.3 C) | same range, rectal preferred under 2yo |
| blood glucose | 70-140 mg/dL | 60-100 mg/dL (neonates lower) |
| respiratory rate | 12-20 breaths/min | 25-50 (infant), 15-30 (child) |
| heart rate | 60-100 bpm | 80-150 bpm (infant), 70-120 bpm (child) |
Clinical Significance
In prehospital care, understanding stemi recognition can mean the difference between a positive patient outcome and a critical miss. A 22-year-old motorcyclist with high-speed ejection. GCS 8, unequal pupils, posturing. Suspect TBI with herniation: hyperventilate, elevate head 30 degrees, rapid transport to trauma center.
Related pharmacology: adenosine at 6mg rapid IV push, then 12mg if needed, indicated for SVT (narrow complex tachycardia).
Practical Example
Field Scenario: An 8-month-old infant is found unresponsive. Parents report fever of 104 F for 2 days. Fontanelle is bulging. Suspect meningitis: manage airway, IV access, rapid transport.
This scenario tests your ability to apply knowledge of stemi recognition under time pressure with incomplete information, exactly the type of decision-making the certification exam assesses.
Overview
ST elevation in 2+ contiguous leads indicating acute myocardial infarction requiring emergent reperfusion therapy. STEMI identification on 12-lead ECG tested on Paramedic exam.
In prehospital assessment, ETCO2 reference range: adult 35-45 mmHg, pediatric 35-45 mmHg. Deviations from these norms guide treatment decisions in the field.
Regulatory Context
Regulatory context for stemi recognition includes federal and state requirements. Healthcare facilities must comply with CMS Conditions of Participation, state licensure requirements, and accreditation standards (Joint Commission or AAAHC). Non-compliance can result in citations, fines, or loss of Medicare/Medicaid reimbursement.
Related Procedures
Procedures related to stemi recognition in the EMS setting:
- AHA ACLS cardiac arrest algorithm: CPR then rhythm check then shock if VF/pVT then epinephrine q3-5min then amiodarone
- Sepsis recognition: qSOFA of 2 or more (altered mentation, RR 22+, SBP 100 or less) then IV fluids 20 mL/kg then early antibiotics if ALS
