ECG Report - Detailed Analysis

Technical Details

• Paper speed: 25 mm/sec (standard)
• Calibration: 10 mm/mV (standard)
• Layout: 12-lead format - Limb leads (I, II, III), Augmented leads (aVR, aVL, aVF), Precordial leads (V1-V6)
• Machine: Maestros ECG recorder

Lead-by-Lead Analysis

Rhythm

• Sinus rhythm - Regular P waves preceding each QRS complex
• Rate: Approximately 75-90 bpm (estimated from R-R intervals at 25 mm/sec)

P Waves

• P waves are visible and upright in leads I, II, aVF, and V4-V6
• Negative (inverted) P wave in aVR - normal finding
• P wave morphology appears normal in limb leads
• Duration: Appears within normal limits (~80-100 ms)
• No evidence of P pulmonale (tall, peaked P) or P mitrale (bifid, broad P)

PR Interval

• Appears normal (~120-200 ms range)
• No obvious prolongation suggesting first-degree AV block
• No short PR with delta wave to suggest pre-excitation (WPW)

QRS Complex

Limb Leads (I, II, III, aVR, aVL, aVF)

• Lead I: Upright, narrow QRS with positive deflection
• Lead II: Tall R waves, narrow QRS - consistent with normal axis
• Lead III: Positive deflection
• aVR: Negative QRS (normal - aVR is typically inverted)
• aVL: Small or biphasic complexes
• aVF: Positive QRS

Precordial Leads (V1-V6)

• V1-V2: Small r wave with dominant S wave (rS pattern) - normal
• V3-V4: Transitional zone - RS or Rs pattern
• V5-V6: Tall R waves with small or absent S waves
• R-wave progression: Appears normal (R waves grow from V1 to V5/V6)
• QRS duration: Narrow (< 120 ms) - no bundle branch block morphology

ST Segment

• No significant ST elevation in any lead
• No significant ST depression observed
• ST segments appear isoelectric (baseline level)
• No acute ischemic pattern visible

T Waves

• Upright T waves in leads I, II, V4-V6 - normal
• T wave inversion in aVR - normal finding
• T waves in V1-V3 may be flat or minimally inverted - can be a normal variant in some individuals
• No hyperacute (tall, peaked) T waves suggesting hyperkalemia or early ischemia

QT Interval

• QT/QTc appears within normal limits visually
• No obvious QT prolongation

Impression / Interpretation

Overall Impression: ECG appears WITHIN NORMAL LIMITS

Clinical Notes & Caveats

1. This appears to be a normal ECG - no acute ischemic changes, no arrhythmia, no conduction defects visible.
2. The image quality limits absolute precision in measuring exact intervals - a digital readout would be more accurate.
3. This ECG analysis is for educational/informational purposes only. Clinical correlation is mandatory. A qualified cardiologist or physician must interpret any ECG in the context of the patient's symptoms, history, and other investigations.
4. If the patient has symptoms (chest pain, palpitations, syncope, dyspnea), the ECG should be formally reviewed by a physician even if it appears normal.
