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 PrR 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
