Stepwise interpretation of ECG - #10 no Dx ID594
- 1. Stepwise interpretation of ECG ID 122 Atrial flutter
- 2. ID 122 – 50 year old man complaining of palpitation
- 3. ID 122 – 50 year old man complaining of palpitation Can you see P waves?
- 4. ID 122 – Atrial flutter with variable AV block – Ventricular rate 107/min. We can see typical waves of atrial flutter with variable AV block – ventricular rate = 107/min.
- 5. ID 122 – Atrial flutter with variable AV block – Ventricular rate 107/min. Let’s now look at the QRS complex. It is positive in I and slightly positive or isoelectric in aVF – The QRS axis is normal.
- 6. ID 122 – Atrial flutter with variable AV block – Ventricular rate 107/min. The QRS duration is normal – There are no signs of right or left bundle branch block or nonspecific block
- 7. ID 122 – Atrial flutter with variable AV block – Ventricular rate 107/min. There no signs of right or left ventricular hypertrophy
- 8. ID 122 – Atrial flutter with variable AV block – Ventricular rate 107/min. The QRS shows no signs of myocardial infarction
- 9. ID 122 – Atrial flutter with variable AV block – Ventricular rate 107/min. Because of the saw-like waves of atrial flutter, it is difficult to assess the T waves in the inferior leads and V6. In the other leads the T waves are normal.
- 10. ID 122 - Final diagnosis - Atrial flutter with variable AV block – Ventricular rate 107/min. Because of the saw-toothed waves of atrial flutter, it is difficult to assess the T waves in the inferior leads and V6. In the other leads the T waves are normal.
