ECG Interpretation

• ID: 10048 | Date: 01-01-2091 | Time: 04:35:22
• Facility: Seema Hospital and Research Centre
• Paper speed: 25 mm/s | Calibration: 10 mm/mV | Filter: 0.25-2.5 Hz AC50
• Machine-calculated heart rate: 91 bpm

Systematic Analysis

1. Rate

• ~91 bpm - normal (normocardia)

2. Rhythm

• Regular rhythm with consistent R-R intervals
• Sinus rhythm - P waves are present and precede every QRS

3. P Waves

• Upright in leads I, II, aVF - consistent with a normal sinus P wave axis
• Inverted in aVR (expected)
• P wave morphology appears normal without notching or significant broadening

4. PR Interval

• Appears within normal limits (~160-180 ms) - no evidence of AV block or pre-excitation

5. QRS Complex

• QRS duration appears narrow (<120 ms) - no bundle branch block pattern
• Axis appears normal (positive in I and aVF)
• No pathological Q waves clearly identifiable

6. ST Segments & T Waves

• ST segments appear isoelectric in most leads
• No obvious ST elevation or depression to suggest acute ischemia
• T waves appear upright in lateral leads

7. QT Interval

• Appears within normal limits for the rate (~91 bpm)

8. Chest Leads (V1-V6)

• Normal R-wave progression from V1 to V6
• No dominant S waves in V5-V6 to suggest right ventricular hypertrophy
• No tall R in V1 or deep S in V1 suggesting posterior MI

Impression

Normal Sinus Rhythm at 91 bpm No acute ischemic changes, no bundle branch block, no significant axis deviation, no hypertrophy pattern identified.
