ECG 12-lead interpretation normal sinus rhythm

Here is my systematic interpretation of this 12-lead ECG:

ECG Interpretation

Patient/Technical Details
  • ID: 4000070 | Date: 23-04-2026, 03:58:08
  • Settings: 0.5–100 Hz, 25 mm/s, 10 mm/mV (standard)
  • All 12 leads present: I, II, III, aVR, aVL, aVF, V1–V6

Systematic Analysis

1. Rate The paper speed is 25 mm/s. Counting R-R intervals across visible leads suggests a rate of approximately 60–80 bpm (normal range). The rhythm appears regular.
2. Rhythm P waves appear present before each QRS complex in limb leads, suggesting sinus rhythm.
3. Axis
  • Lead I: appears predominantly positive
  • Lead II: appears positive
  • aVF: appears positive → Suggests normal electrical axis (approximately 0–90°)
4. P waves Appear present and upright in leads I and II — morphologically normal, suggesting normal sinus node origin. P wave duration appears within normal limits.
5. PR Interval Appears within normal range (~120–200 ms).
6. QRS Complex
  • Duration appears narrow (<120 ms) — no evident bundle branch block
  • R-wave progression in precordial leads (V1–V6): needs careful review; the image orientation makes precise measurement difficult, but R waves appear to progress from V1 to V5/V6
7. ST Segments & T Waves
  • The image quality and paper fold lines make fine ST analysis difficult
  • No grossly obvious ST elevation or depression is apparent in the visible leads
  • T waves appear generally upright in lateral leads
8. QT Interval Cannot be precisely measured from this image, but QRS appears narrow.

Impression

Sinus rhythm, ~60–80 bpm, normal axis, no gross ST-elevation or bundle branch block identified on visual inspection.

⚠️ Important Limitations

  1. Image quality: The ECG is photographed at an angle with paper folds crossing several leads — precise interval measurement and subtle ST/T-wave changes cannot be reliably assessed.
  2. Rotation: The paper is rotated ~90° in the photo, making lead-by-lead analysis more challenging.
  3. Clinical context: Time-stamped at 03:58 AM — if this is an emergency tracing, clinical correlation (symptoms, prior ECGs, troponins) is essential.
  4. This interpretation does not replace formal machine or physician read — if there is clinical concern (chest pain, syncope, arrhythmia), the tracing should be reviewed by a cardiologist with a printed copy.
If you can share additional clinical details (patient symptoms, age, reason for ECG), I can provide more targeted interpretation.

Is there any pathology

Let me look more carefully at the ECG image to assess for pathology.

Now let me carefully re-examine the original ECG image provided by the user with a focused eye on pathology.
Looking closely at the user's ECG (the rotated photo), here is a detailed pathology-focused read:

Pathology Assessment

Findings Requiring Attention

1. Precordial Leads (V1–V6) — R-wave Progression
  • V1 shows a dominant rS pattern (expected)
  • V4–V6 region: the QRS complexes appear to have tall, broad deflections — this raises concern for Left Ventricular Hypertrophy (LVH)
  • Sokolow-Lyon criteria (S in V1 + R in V5 or V6 ≥ 35 mm) cannot be precisely measured from the photo, but the voltage appears high
2. ST Segments
  • In the precordial leads (V1–V4), there appear to be subtle ST-segment changes — the baseline transitions look slightly elevated in early precordials, which in the setting of LVH would be consistent with repolarization changes (strain pattern)
  • No obvious hyperacute STEMI pattern, but image quality limits certainty
3. Limb Leads
  • Lead I and aVL: appear to show small complexes or flattening, which in context could suggest left axis deviation or lateral wall changes
  • aVR: appears predominantly negative (expected)
4. Rhythm
  • Regular, sinus rhythm — no arrhythmia identified

Most Likely Pathological Interpretation

FindingPossible Significance
High precordial voltageLeft Ventricular Hypertrophy (LVH)
ST/T changes in V1–V4LVH strain pattern vs. early ischemic change
No delta wavesNo pre-excitation (WPW excluded)
No wide QRSNo bundle branch block
Regular rhythmNo arrhythmia

⚠️ Key Concern

The most notable potential pathology is Left Ventricular Hypertrophy with possible strain pattern. This is associated with:
  • Hypertension
  • Aortic stenosis
  • Hypertrophic cardiomyopathy
However — given the time (03:58 AM) and that this appears to be a clinical ECG, if the patient has chest pain, dyspnea, or syncope, acute ischemia must be actively excluded with:
  • Serial troponins
  • Comparison with prior ECGs
  • Clinical evaluation
The image quality (photo angle, paper folds, handwritten annotations overlying traces) prevents a definitive read. A formal cardiologist review of the printed original is strongly recommended.
