Dillon’s results

The blood results were all normal, the echocardiogram was normal and showed no structural abnormalities. A 24-hour Holter monitor showed an episode of AF. This episode coincided with Dillon’s diary entry when he had his symptoms.

Below is a copy of his 12 lead ECG which captured his AF.

Note the rhythm is irregular and there are no clear P waves.

Below there is a section of ECG chart without the green highlight points, if you wish to cross-reference it with the interactive chart underneath:

Dillon’s diagnosis is paroxysmal AF. At this stage the GP may decide to refer on to local cardiology department. Check your local policy for the correct referral pathway.
