ECG Analysis

Patient & Machine Data (printed on ECG)

Machine Interpretation (printed)

• Sinus rhythm
• With occasional supraventricular premature complexes (SVPCs/PACs)
• Abnormal left axis deviation
• Abnormal rhythm ECG - doctor advised to confirm the report

Systematic Review

• Sinus rhythm at ~65 bpm - regular background rate
• Occasional PACs (premature atrial complexes) are identified - these are the "supraventricular premature complexes" flagged by the machine

• Machine reports left axis deviation (LAD)
• P/QRS axis: P = 43°, QRS = 81° - note there may be a discrepancy here; an axis of +81° is actually normal. However, the machine flagged LAD, which warrants clinical correlation (could reflect left anterior fascicular block if the morphology supports it)

• PR interval 197 ms - borderline prolonged (normal <200 ms); consistent with first-degree AV block or at its upper limit
• QRS 88 ms - normal, no bundle branch block
• QTc 390 ms - normal (normal <440 ms men, <460 ms women)

• RV5+SV1 = 2.33 mV - this is below the classic Sokolow-Lyon criterion for LVH (>3.5 mV), so no LVH by voltage

• No acute ST-elevation or depression flagged
• No obvious ischemic changes by machine read

Clinical Summary

Recommendations

1. Clinical correlation is mandatory - the machine itself flags "Doctor needs to confirm the report"
2. Check electrolytes (K+, Mg2+) and thyroid function given PACs
3. Repeat ECG in a different position/with better lead placement if artefact is present
4. If LAD is confirmed, evaluate for left anterior fascicular block (LAFB) - look for rS in II, III, aVF and qR in I, aVL
5. If the patient is symptomatic (palpitations, presyncope), consider 24-hour Holter monitor to quantify PAC burden
