- QRS - Markedly Prolonged (320ms)
- Notching lead II ? Atrial activity
- Lead aVF variable QRS morphology
- Absence of typical BBB morphology
- Broad Complex Tachycardia
General DDx would be:
- E.g. sodium channel blockade
- Hyperkalaemia - in isolation or in conjunction with causes above
- SVT with aberrancy / pre-excitation
- Less likely given marked QRS prolongation & QRS morphology
