Wenckebach without a pause!

Cardioscan Memo 47     I A classical Wenckebach sequence without a pause.

I have to learn something new every day!

In my teaching, I always state that a classical Wenckebach sequence must have a pause.

Well I am wrong!!

When I looked up my definition of Wenckebach, I noted that I didn’t include a pause in the definition, but rather a dropped beat only.
