Classical Wenckebach Trigeminy

Report:

Sinus rhythm 98/min

Second degree AV block, Möbitz 1, with 4:3 conduction

Trigeminy

Left atrial abnormality (LAA)

Left bundle branch block

Atypical repolarisation pattern suggests ischæmia

Comment:

The Wenckebach sequences show the classical pattern of decreasing R-R and increasing (but decrementally) P-R intervals.

A 1:1 conduction with PR interval 0.30” is shown below (Fig 152a).
