🚨 CRITICAL ECG ALERT - ACUTE STEMI 🚨
⚠️ EMERGENCY: This patient requires IMMEDIATE emergency intervention. Do NOT delay. Activate the cardiac catheterization lab NOW.
ECG Report Summary
Hospital: Multispeciality Hospital
Date/Time: 2026-06-23 at 07:45:26
Device: CARDIOPRINT
Vital ECG Parameters
| Parameter | Value | Interpretation |
|---|---|---|
| Heart Rate | 75 bpm | Normal |
| PR Interval | 146 ms | Normal (normal: 120-200 ms) |
| QRS Duration | 78 ms | Normal (normal: <120 ms) |
| QT / QTc | 374 / 400 ms | Upper normal range (normal QTc <440 ms) |
| P/QRS/T Axis | 35° / -21° / -33° | Left axis deviation for QRS (-21°) |
| RV5+SV1 | 1.340 mV | Not meeting LVH criteria |
Machine Interpretations (CARDIOPRINT)
The automated system flagged multiple critical findings:
| Finding | Severity |
|---|---|
| CONSIDER ACUTE STEMI | 🔴 CRITICAL |
| ANTERIOR INFARCT - POSSIBLY ACUTE | 🔴 CRITICAL |
| Lateral ST Elevation | 🔴 CRITICAL |
| Inferior ST-T Abnormality | 🟠 HIGH |
| Sinus Arrhythmia | 🟡 MODERATE |
| Leftward Axis | 🟡 MODERATE |
Clinical Interpretation
Rhythm
- Sinus arrhythmia - rate variability present, but overall HR 75 bpm
- QRS axis is leftward at -21°
ST Changes - The Critical Finding
The ECG shows a pattern consistent with extensive anterolateral STEMI:
- Anterior leads (V1-V4): ST elevation - indicating occlusion of the Left Anterior Descending (LAD) artery or proximal left coronary system
- Lateral leads (I, aVL, V5-V6): ST elevation - suggesting involvement extends to the lateral wall
- Inferior leads (II, III, aVF): ST-T abnormalities (possible reciprocal changes or co-existing inferior involvement)
Likely Culprit Vessel
Given anterior + lateral involvement, the most likely culprit is the proximal LAD or left main coronary artery (LMCA) - this is a high-risk, potentially large territory infarction.
⚡ IMMEDIATE ACTION REQUIRED
Within the next 10 minutes:
- Call a Code / Activate STEMI protocol immediately
- Obtain IV access x2, continuous cardiac monitoring, pulse oximetry
- Administer Aspirin 325 mg (chewed) if not contraindicated
- Administer Clopidogrel 600 mg loading dose (or Ticagrelor 180 mg)
- 12-lead ECG confirmed - escalate immediately to cardiologist
Therapeutic Goals (AHA/ACC Guidelines):
- Primary PCI (percutaneous coronary intervention) within 90 minutes of first medical contact (Door-to-Balloon time ≤90 min)
- If PCI not available within 120 min → consider fibrinolytic therapy
- Administer anticoagulation (heparin UFH or enoxaparin)
- Morphine for pain relief only if refractory (with caution - may worsen outcomes per recent data)
- Nitroglycerin - use cautiously, avoid if hypotensive or suspected RV infarct
- Beta-blocker - if hemodynamically stable, no bradycardia or AV block
Labs to order STAT:
- Troponin I or T (STAT + repeat at 3-6 hours)
- CK-MB
- CBC, BMP, PT/INR
- Lipid panel
- BNP/NT-proBNP
- Chest X-ray (portable)
- Echocardiogram (urgent bedside if possible)
Important Notes
- The machine interpretation states: "Interpretation made without knowing patient's gender/age" - patient demographics must be entered to improve accuracy, but this does NOT change the emergency response
- The QTc at 400 ms is borderline - avoid QT-prolonging drugs
- Left axis deviation (-21°) in the setting of anterior STEMI may indicate associated left anterior fascicular block
⚠️ DISCLAIMER: This analysis is for clinical support only. All ECG interpretations must be confirmed by a licensed physician or cardiologist. The clinical context (patient history, vitals, physical exam) must be integrated with ECG findings. Do not delay emergency care.
