VEB: the Compensatory Pause

Report:

Sinus rhythm 62/min

First degree AV block (PR 0.22”)

VEB

Left bundle branch block

Comment:

The P waves are sharply etched in V1 and the one blocked by the VEB is seen quite clearly. There is no need to measure the compensatory pause containing it but, if measured, it would be seen to be (fully) compensatory. In most cases, the blocked P wave is buried and invisible.

The pause itself is, however, as Schamroth put it, “a feeble reed” to lean on in diagnosing VEBs.
