If not I would probably lean towards transcutaneous pacing for this 3° AVB without an escape rhythm? And correct any electrolyte abnormalities

Does the patient have a pacemaker in situ?

This is a very counterintuitive principle in EP...
If a patient has a wide QRS during native conduction due to aberrancy, and there is a tachycardia with a *narrower* QRS, it is *VT* !! 🤯
The principal is that aberrancy should not disappear with faster SVT rate. VT can be narrow (septum, fascicles)

My guess: there appears to be two pacemakers, one which looks sinus (or high on the RA) and the other likely ectopic. The sinus / HRA beats conduct with a narrower QRS but the ectopic ones have a prominent delta wave, possibly suggesting a left-sided accessory pathway?
