ECG Reading - 10 July 2026, 04:18 PM
Machine Measurements
| Parameter | Value |
|---|---|
| Ventricular Rate | 79 BPM |
| PR Interval | 190 ms |
| QRS Duration | 86 ms |
| QT / QTc (Bazett) | 350 / 401 ms |
| P axis | 69° |
| R axis | 9° |
| T axis | 82° |
Settings: 25 mm/s paper speed, 10 mm/mV gain, MAC 5 device
Machine Interpretation (Unconfirmed)
- Normal sinus rhythm
- Nonspecific T wave abnormality
- Abnormal ECG
Lead-by-Lead Findings
Limb leads:
- I: Narrow QRS, R-dominant, upright T, isoelectric ST
- II: Upright P, tall R wave, upright T - classic sinus morphology
- III: Low amplitude, biphasic QRS, flat-to-slightly inverted T
- aVR: Inverted P and T, negative QRS - all normal findings
- aVL: R-dominant QRS, flat-to-slightly inverted/biphasic T - this is likely the source of the "nonspecific T wave abnormality" flag
- aVF: Upright P and T, R-dominant QRS, isoelectric ST
Precordial leads:
- V1: rS pattern, T wave inverted (normal variant)
- V2: rS with slightly larger R than V1 - normal progression
- V3: Transitional zone (RS pattern) - normal
- V4-V6: Progressive R wave dominance with upright T waves - normal R wave progression
Rhythm strip (Lead II): Regular, P before every QRS, consistent RR intervals confirming normal sinus rhythm at 79 BPM
Summary
This ECG shows normal sinus rhythm at 79 BPM with a borderline PR interval of 190 ms (upper limit of normal is 200 ms, so this is within range but approaching first-degree AV block territory). The QTc of 401 ms is normal. The R axis of 9° is within normal limits (normal: -30° to +90°).
The only finding flagged by the machine is a nonspecific T wave abnormality, most likely the flat/biphasic T in aVL. This is a non-specific finding and can be seen in many conditions (positional, ischemia, electrolyte changes, LVH, or simply a normal variant in aVL given its axis orientation).
Note: The handwritten Arabic annotation on the ECG reads "تخطيط طبيعي؟" ("Normal ECG?") - this appears to be a query by the reviewing clinician. The ECG is essentially near-normal with only a nonspecific T wave change; clinical correlation is advised. This reading is for informational purposes and should be confirmed by a licensed physician.
