ECG Analysis — Pushap Devi, Female, 68 Years

Measured Intervals

Machine-Reported Diagnoses (confirmed by report)

1. Sinus Rhythm — Rate 96 bpm, regular
2. Prolonged P-wave — Suggests left atrial enlargement/Right Atrial Enlargement (see below)
3. Poor R-wave Progression (V2–V3) — Anterior forces diminished
4. QS Wave in Lead V1 — Consistent with anterior septal infarction
5. Left Anterior Fascicular Block (LAFB) — Left axis deviation (QRS –45° or more leftward)
6. Right Atrial Enlargement — Tall, peaked P waves
7. Acute Anteroseptal Myocardial Infarction — The most critical finding
8. Slight ST Elevation in V1–V2 — Active injury pattern
9. T-Wave Abnormality in aVL — Lateral ischemia/injury extension

Clinical Interpretation

🔴 Acute Anteroseptal STEMI (Highest Priority)

• ST elevation in V1–V2 with QS morphology in V1 indicates proximal or mid-LAD occlusion
• Poor R-wave progression (V2–V3) with QS in V1 reflects established anterior septal necrosis or a very early acute event
• The machine flags this as "Acute Anteroseptal Myocardial Infarction" — this must be treated as a STEMI equivalent until proven otherwise
• Per Tintinalli's Emergency Medicine: "ST-segment elevation in V1, V2, and V3 from proximal LAD occlusion is a critical finding requiring emergent reperfusion"

🟠 Left Anterior Fascicular Block (LAFB)

• QRS is widened (128 ms) with left axis deviation
• LAFB occurs with block of the anterior fascicle of the left bundle — produces abnormal left axis deviation on ECG
• Per Harrison's: "A block in the anterior fascicle of the left bundle system (LAFB or hemiblock) produces left axis deviation"
• LAFB in the setting of acute anterior MI indicates the infarct is encroaching on the conduction system — increases risk of progression to complete heart block

🟡 Right Atrial Enlargement

• Prolonged/tall P-waves suggest right atrial enlargement, possibly due to pulmonary hypertension or cor pulmonale as a pre-existing condition

🟡 Borderline QTc Prolongation (474 ms)

• May be a consequence of ischemia or electrolyte disturbance — monitor closely; avoid QT-prolonging drugs

Key Concern: LAD Territory Involvement

• QS pattern in V1
• Poor R-wave progression V2–V3
• Slight ST elevation V1–V2
• LAFB (conduction system involvement)
• T-wave abnormality in aVL

Immediate Clinical Actions Required

⚠️ Clinical Disclaimer: This analysis is intended to support — not replace — clinical judgment. A qualified cardiologist must review the original ECG tracing and assess the patient clinically. Given the acute anteroseptal MI pattern in a 68-year-old female, emergent management is indicated.
