ECG Interpretation - Sreejith, 40M | 5 July 2026
Technical Details
- Paper speed: 25 mm/s | Gain: 10 mm/mV (standard calibration)
- Filters: AC 50Hz + EMG 25Hz
Systematic Analysis
| Parameter | Finding |
|---|---|
| Rate | ~60-65 bpm |
| Rhythm | Regular sinus rhythm |
| Axis | Normal (~+60°) |
| P waves | Normal morphology, amplitude <2.5 mm, duration <120 ms - no atrial enlargement |
| PR interval | ~160 ms (normal, 120-200 ms) |
| QRS duration | ~80-90 ms (narrow, normal) |
| QRS morphology | Normal R-wave progression V1-V6; transition at V3/V4; no pathological Q waves; no LVH/RVH criteria |
| ST segments | Isoelectric in all leads - no elevation or depression |
| T waves | Upright in I, II, aVL, aVF, V3-V6; inverted in aVR (normal) and V1 (normal); mildly flat/biphasic in III (common normal variant) |
| QTc | Within normal limits (~400 ms) |
Impression
Normal 12-lead ECG.
- Normal sinus rhythm at 60-65 bpm
- Normal cardiac electrical axis
- No evidence of:
- Acute ischemia or infarction (no ST elevation/depression, no pathological Q waves, no hyperacute T waves)
- Bundle branch block or conduction delay
- Ventricular or atrial hypertrophy
- Arrhythmia
- QT prolongation
This is consistent with the machine printout annotation of "Normal Sinus Rhythm - Cardiac electric axis normal."
Note: This interpretation is for informational purposes. The ECG paper itself notes "Report needs physician confirmation" - formal over-read by a qualified clinician is recommended before any clinical decision-making.
