Can you see P waves?

ID 383 – Atrial fibrillation with controlled ventricular rate (66/min)
There are no P waves. There are fibrillatory waves that vary in size and shape.The ventricular rhythm is irregularly irregular (atrial fibrillation) – The rate is 66/min

ID 383 – Atrial fibrillation with controlled ventricular rate (66/min)
Let’s now look at the QRS complexes: There is normal QRS axis (between 0 and 90 degrees)

ID 383 – Atrial fibrillation with controlled ventricular rate (66/min)
The QRS duration is normal : There is no right bundle branch block, left bundle branch block or non specific block ‐

ID 383 – Atrial fibrillation with controlled ventricular rate (66/min)
There is no right ventricular hypertrophy or left ventricular hypertrophy

ID 383 – Atrial fibrillation with controlled ventricular rate (66/min)
There are no QRS signs of myocardial infarction –There are normal ST segment and normal T waves

ID 383 Final Diagnosis: Atrial fibrillation with controlled ventricular rate (66/min) No other abnormalities
There are no QRS signs of myocardial infarction –There are normal ST segment and normal T waves
