ECG Interpretation

• Date: 26-04-2026, Time: 01:03:23
• Speed: 25 mm/s
• Gain/Calibration: 10 mm/mV
• Heart Rate (machine-read): ♥ 104 bpm
• Machine: SEMIP V1.7
• Leads visible: I, II, III, aVR, aVL, aVF (limb leads) and V1–V6 (precordial leads)

Systematic Analysis

1. Rate

• ~104 bpm (confirmed by machine readout) — Tachycardia

2. Rhythm

• P waves appear present before QRS complexes in the visible leads, suggesting sinus tachycardia
• The RR intervals appear regular

3. Axis

• The image quality and orientation make precise axis calculation difficult, but the QRS morphology in the visible limb leads suggests the axis is within or near the normal range. No obvious extreme axis deviation visible.

4. P Waves

• P waves appear to precede each QRS — consistent with sinus origin
• Morphology is difficult to assess precisely due to image quality and crumpling of the paper

5. PR Interval

• Appears to be within normal limits (~120–200 ms) — no obvious prolongation or shortening visible

6. QRS Complex

• QRS complexes appear narrow (< 120 ms) — no obvious bundle branch block pattern
• QRS morphology appears consistent across leads

7. ST Segments & T Waves

• The image resolution and paper crumpling limit definitive assessment, but:
  • In the inferior leads (II, III, aVF): No obvious ST elevation or depression seen
  • In the precordial leads (V1–V6): The lower portion of the strip (V4–V6 region) shows what appears to be somewhat irregular/variable waveforms — this may reflect artifact from the crumpled paper rather than true pathology
• No clearly obvious ST elevation or depression that would suggest acute coronary syndrome, but this cannot be ruled out with certainty due to image quality

8. QT Interval

• Difficult to measure precisely from this image

Impression

Sinus tachycardia at ~104 bpm with no obviously definitive pathological changes identifiable on this image.

• Physiological (pain, anxiety, fever, exertion, dehydration)
• Anemia
• Thyrotoxicosis
• Pulmonary embolism
• Cardiac causes (early heart failure, myocarditis)
• Medications/substances

⚠️ Important Limitations

1. Image quality is significantly limited — the ECG paper is crumpled, folded, and photographed at an angle, making precise interval measurement and ST/T-wave analysis unreliable.
2. Part of the strip is obscured by a white paper/card in the lower right portion.
3. This interpretation is not a substitute for formal ECG reading by a cardiologist with the original, unfolded tracing.
4. The handwritten annotation (appears to read "Дукесонова Ф" — a patient name in Cyrillic/Uzbek) is visible on the strip.
