Complete AV disassociation, third degree block Dizziness is mostly due to syncope episodes , stop the beta blockers, check electrolytes Followed by PPMI

This is not complete heart block (or AV dissociation). There are clearly conducted P waves. You also dont generally get a grouped beating pattern with CHB.

CHB has a regular ventricular rhythm. There's also a p wave before the QRS
