| P axis | 92 ms | — |
| QRS axis | 66° | 0–90° ✅ |
Systematic Analysis
Rate: 78 bpm — normal
Rhythm: Regular. The machine interpretation confirms Normal Sinus Rhythm — P waves are upright in I and II, inverted in aVR, consistent with a sinus origin.
Axis: +66° — normal axis
P waves: Visible and upright in leads I, II; inverted in aVR. Normal morphology. PR interval 170 ms — normal, no heart block.
QRS complexes:
- Duration 82 ms — narrow, no bundle branch block
- Normal R-wave progression across precordial leads (V1–V6): small r in V1 progressing to dominant R in V5/V6
- No pathological Q waves identified
ST segments:
- No significant ST elevation or depression visible
- Isoelectric baseline throughout
T waves:
- Upright in I, II, V4–V6
- T-wave inversion in aVR — normal finding
- V1–V3: T waves appear slightly flat/biphasic, which can be a normal variant in females, but worth noting
QT/QTc: 414 ms — within normal limits (< 440 ms for females)
Machine Interpretation
"Normal sinus rhythm. Normal ECG." (Unconfirmed — requires physician sign-off)
Summary
This ECG is within normal limits for an adult female:
- Normal sinus rhythm at 78 bpm
- Normal axis (~66°)
- Normal intervals (PR, QRS, QTc)
- No ischemic changes, no conduction abnormalities, no arrhythmia
One minor observation: Slightly flat/biphasic T waves in V1–V2 are a normal variant in females and do not require further workup in isolation. If there is a clinical concern (chest pain, dyspnea), correlation with symptoms and troponin is always appropriate.
