I’m busy updating my ECG collection so I’m using some of the older ECG’s I’ve collected. Unfortunately many of these, including this week’s ECG, don’t have any associated clinical information. I will try and track down some information on this case and will update the post if I find any.
Even without any clinical information it’s still a nice ECG 🙂

- QRS – Markedly Prolonged (320ms)
- Notching lead II ? Atrial activity
- Lead aVF variable QRS morphology
- Absence of typical BBB morphology
- Broad Complex Tachycardia
I think this ECG would benefit from having a real patient / clinical case attached to narrow down the differential list.
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
