Can you see P waves?

ID 619 – Sinus rhythm with frequent premature ventricular complexes

Yes – There is sinus rhythm, rate 100/min, with frequent premature ventricular complexes

ID619 - Sinus rhythm with frequent premature ventricular complexes

The PR interval is normal – There is no left or right atrial enlargement

ID619 - Sinus rhythm with frequent premature ventricular complexes

The PR interval is normal – There is no left or right atrial enlargement

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)

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

ID619 - Sinus rhythm with frequent premature ventricular complexes

There is no evidence of right or left ventricular hypertrophy

ID619 - Sinus rhythm with frequent premature ventricular complexes

There are no QRS signs of myocardial infarction

ID619 - Sinus rhythm with frequent premature ventricular complexes

The ST segment and T waves are normal

ID619 – Final diagnosis: Sinus rhythm with frequent premature ventricular complexes Otherwise, a normal ECG

The ST segment and T waves are normal
