A 68-year-old man presented to the emergency department after an accidental fall. An ECG was performed which showed sinus rhythm at a rate of 100 bpm with frequent premature ventricular complexes. The PR interval and QRS complexes were normal, indicating no signs of conduction abnormalities. There was also no evidence of chamber enlargement, myocardial infarction, or ischemia. The final diagnosis was sinus rhythm with frequent premature ventricular complexes, but an otherwise normal ECG.

Stepwise interpretation - ECG #3
- 1. Stepwise interpretation of ECG ID 619
- 2. ID 619 68 year old man in the Emergency Department after an accidental fall
- 3. ID 619 68 year old man in the Emergency Department after an accidental fall Can you see P waves?
- 4. ID 619 – Sinus rhythm with frequent premature ventricular complexes Yes – There is sinus rhythm, rate 100/min, with frequent premature ventricular complexes
- 5. ID619 - Sinus rhythm with frequent premature ventricular complexes The PR interval is normal – There is no left or right atrial enlargement
- 6. ID619 - Sinus rhythm with frequent premature ventricular complexes The PR interval is normal – There is no left or right atrial enlargement
- 7. ID619 - Sinus rhythm with frequent premature ventricular complexes Let’s now look at the QRS complexes: There is normal QRS axis (between O and 90 degrees)
- 8. ID619 - Sinus rhythm with frequent premature ventricular complexes The QRS complexes that follow the P waves have a normal duration – There is no right bundle branch block, left bundle branch block or non-specific block
- 9. ID619 - Sinus rhythm with frequent premature ventricular complexes There is no evidence of right or left ventricular hypertrophy
- 10. ID619 - Sinus rhythm with frequent premature ventricular complexes There are no QRS signs of myocardial infarction
- 11. ID619 - Sinus rhythm with frequent premature ventricular complexes The ST segment and T waves are normal
- 12. ID619 – Final diagnosis: Sinus rhythm with frequent premature ventricular complexes Otherwise, a normal ECG The ST segment and T waves are normal
