Atrial Pacing & Intercalated VEBs

Report:

Atrial pacemaker rhythm

VEBs, intercalated (interpolated)

Comment:

The VEBs show the diagnostically important left rabbit ear and different initial vector from the paced beats. They also prolong the subsequent A-R intervals through concealed retrograde conduction to the AV node. The cycle containing the VEB is thus slightly prolonged; the subsequent cycle is correspondingly shortened.

More of the same, with larger pacing spikes, is shown below on this page. 156. How many supraventricular complexes are replaced by the FLBs (funny-looking beats)?
