Now let me provide a thorough ECG analysis based on careful visual inspection of the tracing:
ECG Analysis - Goutam Ghori (05/06/2026, 10:20 AM)
Technical Details:
- Speed: 25 mm/s | Gain: 10 mm/mV
- 12-lead standard recording
- AC50Hz filter active
Rate
The R-R intervals appear regular. Counting approximately 4-5 large boxes between R waves suggests a heart rate of approximately 75-85 bpm (normal sinus range).
Rhythm
The rhythm appears regular with consistent P-wave morphology preceding each QRS complex. This is consistent with normal sinus rhythm.
Axis
- Lead I: upright QRS
- Lead aVF: upright QRS
- This places the axis in the normal quadrant (0° to +90°)
P Waves
P waves appear present and upright in leads I, II, aVF - consistent with sinus origin. P wave duration and morphology appear normal. No obvious bifid (P mitrale) or tall peaked (P pulmonale) pattern visible at this resolution.
PR Interval
Appears within normal limits (~120-200 ms range; roughly 3-5 small boxes at 25 mm/s). No obvious first-degree AV block.
QRS Complex
- Duration appears narrow (<120 ms) - no bundle branch block pattern
- Tall R waves are visible in the lateral leads (V5, V6 region / leads I, aVL)
- Deep S waves visible in the right precordial leads (V1-V3)
- This pattern raises concern for Left Ventricular Hypertrophy (LVH)
LVH Voltage Criteria:
- Sokolow-Lyon: S in V1 + R in V5 or V6 > 35 mm
- Cornell: R in aVL + S in V3 > 28 mm (men)
- The tall precordial voltage pattern visible here is suggestive of LVH
ST Segment & T Waves
- In the lateral leads (I, aVL, V5-V6), there appears to be ST depression with T-wave inversion - this is the classic "LVH strain pattern" (also called repolarization abnormality)
- In V1-V3, T waves appear upright (reciprocal to the lateral changes)
- No obvious acute ST elevation to suggest STEMI
Q Waves
No pathological Q waves are clearly identified (Q waves > 1/4 R wave height or > 40 ms duration).
Summary / Impression
| Finding | Assessment |
|---|---|
| Rhythm | Normal Sinus Rhythm (~75-85 bpm) |
| Axis | Normal |
| PR interval | Normal |
| QRS duration | Normal (narrow) |
| Key finding | Left Ventricular Hypertrophy with strain pattern |
| ST-T changes | Lateral ST depression/T-wave inversion (LVH strain) |
| Acute ischemia | Not definitively identified on this tracing |
Clinical Interpretation
The ECG shows features strongly suggestive of Left Ventricular Hypertrophy (LVH) with associated repolarization changes (strain pattern). This is commonly seen in:
- Systemic hypertension (most common cause)
- Hypertrophic cardiomyopathy
- Aortic stenosis
- Long-standing volume overload (aortic/mitral regurgitation)
Important Disclaimer
This is an automated AI interpretation for educational reference only. ECG analysis requires clinical correlation with the patient's history, symptoms, physical examination, and serial tracings. The image quality and orientation (tracing appears slightly rotated/angled in the photo) limit absolute certainty. A qualified cardiologist or physician must review and interpret this ECG for any clinical decision-making.
Recommended follow-up:
- Echocardiogram to assess LV wall thickness and function
- Blood pressure measurement (hypertension workup)
- Comparison with prior ECGs if available
- Clinical correlation with patient's symptoms (chest pain, dyspnea, syncope)
