ECG Interpretation

Rate

Rhythm

• The rhythm appears regular
• P waves are visible before each QRS complex in the limb leads, suggesting sinus rhythm

Axis

• Lead I: positive QRS
• aVF: appears positive/equiphasic
• This suggests a normal or left axis orientation

P Waves

PR Interval

QRS Complex

• QRS complexes appear narrow in most limb leads
• In the precordial leads (V1-V6): there is a transition from negative-dominant (V1-V2) to positive-dominant (V4-V6), which is normal R-wave progression
• V1 shows what looks like a small r wave followed by a deep S wave - consistent with normal morphology, though the image angle makes precise measurement difficult

ST Segments & T Waves

• In leads V1-V3, there may be some ST changes worth noting - the image quality and angle make it hard to be definitive, but the T-waves in V1-V2 appear inverted or flat
• Leads V4-V6 appear to have upright T waves
• No obvious ST elevation suggesting acute STEMI pattern

Notable Findings to Flag

1. T-wave inversions in V1-V2 - can be a normal variant, but can also suggest right ventricular strain or anterior ischemia
2. The aVR lead appears to have a prominent negative deflection, which is normal
3. No obvious delta waves (WPW pattern)
4. No obvious bundle branch block morphology (QRS does not appear widened)

Summary

This ECG appears to show sinus rhythm at a normal rate with no obvious acute ST-elevation myocardial infarction (STEMI) pattern. There may be T-wave changes in the anterior leads (V1-V2) that warrant clinical correlation.
