AV with slow ventricular response.

The rate is 40BPM.

In the good old days this was digitalis toxicity until proven otherwise.

The clue is Bifascicular block.

Many cardiologists are reluctant to call this complete heart block as there is no AV dissociation.

Don’t be scared to call this complete heart block because that is what it is!!

Permanent pacing required.
