Here is the full ECG interpretation based on both images:
ECG Interpretation
Patient: Male, born 1989 (approx. 37 years old)
Institution: Can Tho University of Medicine and Pharmacy - Emergency Department
Date: July 8, 2026, ~22:22-22:23
Settings: 10 mm/mV (limb leads), 5 mm/mV half-standardization (precordial leads V1-V6), paper speed 25 mm/s
Technical Quality
- All 12 leads present: I, II, III, aVR, aVL, aVF, and V1-V6
- Mild baseline wander in V4-V6 (likely respiratory or movement artifact - not clinically significant)
- Filter: 50 Hz / 35 Hz applied
Measurements
| Parameter | Value | Normal Range | Assessment |
|---|---|---|---|
| Heart Rate | ~65-79 bpm (regular) | 60-100 bpm | Normal |
| P wave duration | 0.08 s | <0.12 s | Normal |
| P wave amplitude | 1 mm | <2.5 mm | Normal |
| PR interval | 0.12 s | 0.12-0.20 s | Normal |
| QRS duration | 0.08 s | <0.10 s | Normal (narrow) |
| QT interval | 0.40 s | <0.44 s | Normal |
| Cardiac axis | +45° (intermediate) | -30° to +90° | Normal axis |
| Sokolov-Lyon index | <35 mm | <35 mm | No LVH |
Systematic Analysis
1. Rhythm
Regular sinus rhythm. Every QRS is preceded by a normal upright P wave in leads I and II, with constant PR interval. P waves are inverted in aVR (expected normal finding). No ectopic beats, no pauses.
2. Rate
65-79 bpm - normal (the slight discrepancy between readings reflects two slightly different acquisition moments; both are within normal range).
3. Axis
+45 degrees - intermediate/normal axis. QRS positive in leads I and II; no left axis or right axis deviation.
4. P Waves
Normal duration (0.08 s), normal amplitude (1 mm), rounded morphology - typical sinus origin. No signs of atrial enlargement (no bifid or peaked P waves).
5. PR Interval
0.12 s - lower end of normal. No first-degree AV block (which would be >0.20 s). No pre-excitation pattern (no delta waves, no short PR with wide QRS).
6. QRS Complexes
- Narrow (0.08 s) - no bundle branch block
- Normal R-wave progression V1 to V6
- No pathological Q waves - no evidence of prior myocardial infarction
- Sokolov-Lyon index <35 mm (even accounting for V1-V6 half-standardization at 5 mm/mV) - no left ventricular hypertrophy
7. ST Segments
Isoelectric in all leads. No ST elevation (no STEMI pattern). No ST depression (no ischemia/NSTEMI pattern).
8. T Waves
Upright and normal in I, II, and V1-V6. Inverted in aVR (normal). No T-wave inversions suggesting ischemia. No hyperacute T waves.
9. QT Interval
0.40 s - within normal limits. No long QT syndrome concern.
Conclusion
NORMAL ECG - Regular Sinus Rhythm, 65-79 bpm
The machine interpretation (in Vietnamese) confirms: "NHỊP XOANG ĐỀU, TẦN SỐ 65 LẦN/PHÚT" - Regular sinus rhythm, 65 bpm.
There are no signs of:
- Acute myocardial infarction or ischemia
- Arrhythmia or conduction block
- Chamber enlargement or hypertrophy
- Electrolyte disturbances
- Long QT or pre-excitation
Clinical context note: The request was an emergency bedside ECG in the context of a cervical spine/neck injury (dislocation/sprain). The cardiac assessment is reassuring - the ECG does not suggest any cardiac complication from the trauma. Follow-up should focus on the underlying cervical injury management.
This interpretation is based on image analysis and is intended to support - not replace - clinical review by a qualified physician.
