‘VT’ versus ‘SVT with aberrancy’.
The long list of VT "suggestive" ECG features is difficult to recall and apply in real time.
How can we simplify things?
Here is my ABCDE approach – five simple Qs to ask:

It’s been a while ⏰
Stay tuned. The team and I @LITFLblog are working on the biggest addition to the LITFL ECG Library to date.

The ABCDE approach to VT v SVT
Came up with this last year when preparing an ECG talk for ICEM
Still my favourite piece of work giving a simplified, practical approach to a complex topic

This is by far the best website for anything ECG. Whenever I read something that is new to me I just look it up on their website and read their straight-to-the-point articles. Check it our for anybody interested (they even have 150 ECG questions!)

The power of #FOAMed through @LITFLblog
Knowing how to switch between system 1 and 2 thinking is one of the most important skills of an Emergency Clinician.
When do you choose to employ a System 2 approach?
Here are three situations for me. Comment with your own so we can improve our approach 👇🧵
By popular demand, the ABCDE approach is now an established part of the @LITFLblog ECG Library.
I've also added an optional F -- check out the post to learn more.

In VT, time to peak of depolarisation is often delayed at > 40ms in V1 or V2.
SVT with aberrancy displays initial sharp QRS deflections that arise from the preserved bundle branch.
Remember, if in doubt, always treat as VT.
In unstable patients, the decision is easy – they need electricity.
In stable patients, consider trying one of the three methods discussed in this thread to further differentiate the rhythm:
