The library doesn't have a dedicated cardiology ECG/infarction section beyond anesthesia. I have the ECG image clearly visible and the machine's auto-analysis printed on the strip. Let me provide a thorough interpretation directly from the ECG findings.
ECG Interpretation
Date: 19-05-2026 | Time: 08:14 PM | Patient: Male
Machine-Reported Parameters
| Parameter | Value | Reference |
|---|---|---|
| Heart Rate | 105 bpm | 60–100 bpm |
| P wave | 98 ms | ≤120 ms ✓ |
| PR interval | 146 ms | 120–200 ms ✓ |
| QRS duration | 104 ms | <120 ms ✓ (borderline) |
| QT/QTc | 350/463 ms | QTc >440 ms = prolonged ⚠️ |
| RV5/SV1 | 0.507/1.365 mV | — |
Diagnoses (Confirmed by Machine + Visual Analysis)
1. 🔴 Sinus Tachycardia (HR 105 bpm)
- Regular rhythm with upright P waves before every QRS in leads II, aVF.
- Rate >100 bpm. Likely a secondary finding — needs clinical correlation (pain, fever, hypovolemia, anxiety, thyrotoxicosis, heart failure, medications).
2. 🟠 Borderline Prolonged QTc (463 ms)
- QTc >440 ms in males is prolonged; 463 ms is mildly elevated.
- Risk for Torsades de Pointes — check electrolytes (K⁺, Mg²⁺, Ca²⁺), medications (QT-prolonging drugs), and thyroid function.
3. 🟡 Possible Left Atrial Abnormality (P-wave morphology)
- Suggests left atrial enlargement/strain — association with hypertension, mitral valve disease, LV dysfunction.
4. 🔴 Possible Anteroseptal Infarct – Age Undetermined (Most Clinically Significant)
ECG evidence visible:
- Poor R-wave progression in V1–V3/V4: R waves fail to grow normally across the precordial leads, with dominant S waves or near-absent R waves in V1–V3.
- Deep QS pattern in V1–V2: consistent with loss of anterior septal forces due to infarction of the LAD (left anterior descending artery) territory.
- The term "age undetermined" means there are no acute ST-elevation changes — this is likely an old (healed) anteroseptal MI, not an acute STEMI.
"Age undetermined" vs. acute:
- Acute STEMI: ST elevation ≥1 mm in ≥2 contiguous leads (not seen here)
- Old/chronic MI: pathological Q waves or QS pattern without ST elevation ✓ (as seen here)
Clinical Correlation Needed
| Finding | Next Step |
|---|---|
| Anteroseptal infarct pattern | Troponin I/T, prior ECG comparison, echocardiography |
| Sinus tachycardia | Identify and treat underlying cause |
| Prolonged QTc (463 ms) | Serum K⁺, Mg²⁺, Ca²⁺; medication review; avoid QT-prolonging drugs |
| Left atrial abnormality | BP measurement, echo for LA size and LV function |
Summary
This ECG shows sinus tachycardia with an old anteroseptal myocardial infarction pattern (QS in V1–V2, poor R-wave progression V1–V4), borderline QTc prolongation, and possible left atrial enlargement. The most important finding is the anteroseptal infarct pattern — this patient should have troponins checked urgently to rule out any new ischemic event, and an echocardiogram to assess wall motion and LV function. Prior ECG comparison is essential to determine if this is truly old vs. evolving.
