ECG Analysis - 12-Lead Report
Patient details (from strip): Female, 10 years old | Heart Rate: 101 bpm | 6-channel format
Systematic Findings
| Parameter | Finding |
|---|---|
| Rate | ~101 bpm (borderline sinus tachycardia) |
| Rhythm | Regular sinus rhythm |
| Axis | Normal (0° to +90°) |
| PR interval | Normal (~120-160 ms), consistent 1:1 AV conduction |
| QRS duration | Narrow (<100 ms) - no bundle branch block |
| QT/QTc | Visually within normal limits for rate |
Waveform Analysis
- P waves: Normal morphology and duration; upright in I, II, aVF; inverted in aVR (normal)
- QRS complex: Normal R-wave progression across precordials (V1 rS pattern → transition at V3-V4 → tall R in V5-V6); no pathological Q waves; no voltage criteria for LVH or RVH
- ST segments: Isoelectric in all leads - no ST elevation or depression
- T waves: Upright in I, II, V2-V6; inverted in aVR (normal); no hyperacute, flattened, or deeply inverted T waves
Conclusion
This ECG shows borderline sinus tachycardia (101 bpm) with no other significant abnormality.
The only notable finding is the heart rate of 101 bpm, which is at the upper boundary of normal for a 10-year-old child (normal upper limit in children this age is approximately 100-110 bpm, so this is at the borderline or within normal variation). There are no signs of:
- Acute ischemia or STEMI
- Bundle branch block or conduction delay
- Ventricular hypertrophy
- Arrhythmia
- Prior myocardial infarction
Clinical note: A heart rate of 101 bpm in a child can be physiological (e.g., anxiety, fever, dehydration). Clinical correlation is recommended. This ECG interpretation is for educational/informational purposes and should be confirmed by a qualified physician.
