I now have all I need from the library and the ECG images. Here is a full analysis:
ECG Analysis
Machine report (from the printout):
| Parameter | Value | Normal Range |
|---|---|---|
| Heart Rate | 79 bpm | 50-100 bpm |
| PR Interval | 142 ms | 90-200 ms |
| QRS Duration | 98 ms | 75-110 ms |
| QT/QTc | 364/397 ms | Males: 390-450 ms |
| P/QRS/T axis | 67° / 51° / 45° | -30 to +90° |
| RV5/SV1 | 1.280/0.181 mV | - |
| RV5+SV1 | 1.461 mV | <3.5 mV (Sokolow-Lyon) |
Machine interpretation: Sinus rhythm - Normal ECG
My Analysis
Rhythm: Sinus rhythm. The P waves are upright and precede every QRS complex, indicating the impulse originates normally from the SA node.
Rate: 79 bpm - completely normal resting heart rate.
PR interval (142 ms): Normal. The normal range is 90-200 ms. This rules out first-degree AV block (which would be >200 ms) and pre-excitation syndromes like WPW (which would be short with a delta wave).
QRS duration (98 ms): Normal (under 110 ms). No bundle branch block. Ventricular conduction is intact.
QTc (397 ms): Normal for males (normal is 390-450 ms). No QT prolongation, which means no significant risk of torsades de pointes from this reading alone.
Axis (QRS 51°): Normal axis. Ranges from -30° to +90°, so 51° is well within normal limits.
Voltage (RV5+SV1 = 1.461 mV): Well below the Sokolow-Lyon criterion of 3.5 mV for left ventricular hypertrophy. No LVH by voltage criteria.
Looking at the tracing itself:
- Limb leads (I, II, III, aVR, aVL, aVF): Regular, well-formed complexes. No ST elevation or depression visible. P waves appear normal.
- Precordial leads (V1-V6): Normal R wave progression - small r in V1 transitioning to taller R waves across to V6. No pathological Q waves visible. No ST segment changes suggesting ischemia or injury.
- The T waves appear upright in the lateral leads, which is normal.
Bottom Line
This is a completely normal ECG. The machine interpretation is correct - sinus rhythm with all intervals and morphology within normal limits. There are no signs of:
- Ischemia or infarction
- Arrhythmia
- Conduction disease
- Chamber enlargement or hypertrophy
- Repolarization abnormality
Disclaimer: This is an educational analysis only and does not constitute a clinical diagnosis. The printout itself notes the interpretation was made without knowing the patient's gender/age. A qualified physician should always review ECGs in the context of the patient's full clinical picture.
