A 12-lead ECG is required for diagnosis. The characteristic features of AV dissociation are: Dissociated P Waves: These appear as "P waves marching through the QRS complex." PR intervals might appear getting progressively shorter.

3rd degree AV block is characterised by complete AV dissociation, with no supraventricular impulses conducted to the ventricles.
Ventricular rate is slower than atrial rate (there is complete AV block). Slow atrial rate with a faster junctional or ventricular rate (there is no AV block).
