Patient Name: Sean Richards
Age/Sex: 45-year-old male
Clinical Context: Admitted for cirrhosis with bleeding esophageal varices secondary to portal hypertension. Presented with hematemesis, fatigue, and mild hypotension.

Rate: 125 beats per minute
Rhythm: Sinus Tachycardia
Axis: Normal
Intervals:

• PR Interval: ~0.16 seconds (within normal limits)

• QRS Duration: ~0.08 seconds (normal)

• QT Interval: Appears shortened appropriately for rate

Waveform Analysis:

• P Waves: Present before every QRS complex; upright in leads I, II, and aVF — consistent with sinus origin.

• QRS Complex: Narrow, uniform morphology across all leads; no evidence of bundle branch block or pathologic Q waves.

• ST Segment: Slight upsloping noted but no ST elevation or depression suggestive of ischemia.

• T Waves: Upright, normal amplitude; no T-wave inversion or hyperacute changes.

Interpretation Summary:

• Sinus tachycardia at 125 bpm

• Regular rhythm with intact AV conduction

• Normal axis and intervals

• No acute ischemic changes or ectopy
