Here is a detailed interpretation of this ECG:
ECG Interpretation
Technical Details (from printed labels)
- Speed: 25 mm/s
- Gain: 10 mm/mV
- Filter: 0.5-35 Hz, AC50
- Mode: 2×5.0s + 1r
- Heart Rate: 61 bpm (printed ♥61)
- P/QRS/T intervals: 66/34/71 ms (visible on margin)
- RV5/SV1: 1.964/0.267 mV
- Machine: Glasgow algorithm V28.6.0 (D H Mavelikara, Cardiar)
Systematic Analysis
1. Rate
~61 bpm - Normal (normocardia). Confirmed by the machine printout.
2. Rhythm
Regular rhythm with visible P waves preceding each QRS complex - consistent with normal sinus rhythm.
3. P Waves
P waves are present and upright in leads I, II, and aVF - confirming sinus origin.
4. PR Interval
Printed as 66 ms - this appears to be the P wave duration. The PR interval itself appears to be within normal limits visually (~120-200 ms range), though the exact machine measurement should be correlated.
5. QRS Duration
34 ms (printed) - this is narrow, ruling out bundle branch block or ventricular conduction delay.
6. QRS Axis
With upright QRS in lead I and upright in aVF, the axis is in the normal range (0° to +90°).
7. Voltage
- RV5 = 1.964 mV and SV1 = 0.267 mV
- Sum RV5 + SV1 = ~2.23 mV - this is borderline/normal (LVH criterion by Sokolow-Lyon is >3.5 mV, so this does not meet LVH criteria).
8. ST Segments
- No definite ST elevation or depression is clearly visible in the limb leads (I, II, III, aVR, aVL, aVF).
- The precordial leads (V1-V6) should be carefully reviewed - the image quality and orientation make it slightly difficult to assess the full precordial territory.
9. T Waves
T waves appear upright in leads I and II. T-wave morphology appears normal in the visible leads.
10. Notable Observations
- The QRS complexes appear to show some notching or fragmentation in certain leads - this would warrant clinical correlation.
- No obvious delta waves (ruling out Wolff-Parkinson-White at first glance).
- No clearly visible pathological Q waves.
Summary / Impression
| Parameter | Finding |
|---|---|
| Rate | 61 bpm - Normal |
| Rhythm | Normal Sinus Rhythm |
| Axis | Normal |
| PR interval | Normal |
| QRS duration | Narrow (34 ms - normal) |
| LVH | Not met by voltage criteria |
| ST changes | No obvious acute ischemic changes |
| T waves | Appear normal |
Overall: This ECG appears to show normal sinus rhythm at 61 bpm with no overt signs of acute ischemia, bundle branch block, or significant axis deviation. No LVH by Sokolow-Lyon criteria.

ECG interpretation from photographs may miss subtle findings. A formal read by a cardiologist is recommended for clinical decision-making.
