Machine Interpretation
- 001: Sinus Rhythm
- 171: Normal ECG
Manual Review
Rate & Rhythm:
- Heart rate 77 bpm — normal sinus rhythm
- Regular R-R intervals
- P waves present and upright in II, aVF → sinus origin confirmed
Conduction:
- PR interval 150 ms — normal (no first-degree block)
- QRS 80 ms — narrow, normal ventricular conduction
- No bundle branch block
Axis:
- QRS axis at -8° — technically leftward but within the borderline normal range (normal: -30° to +90°). Not pathological left axis deviation.
Repolarization:
- QTc 414 ms — normal, no QT prolongation
- No ST elevation or depression visible
- No T-wave inversions described
Voltage:
- RV5+SV1 = 0.382 mV — no left ventricular hypertrophy by Sokolow-Lyon criteria
Summary
Normal ECG in a 49-year-old female. Sinus rhythm at 77 bpm. Normal PR, QRS, and QTc intervals. No ischemic changes, no hypertrophy, no conduction abnormality. The QRS axis is mildly leftward (-8°) but within acceptable limits.
Clinical Note
This ECG does not show evidence of:
- Acute MI or ischemia
- Arrhythmia
- Bundle branch block
- Hypertrophy
- QT prolongation
The machine interpretation of "Normal ECG" is supported by the measured parameters. Clinical correlation with the patient's symptoms is always recommended.
