Intermittent Bundle Branch Block
Bundle branch and the other fascicular blocks create a challenge for the arrhythmia algorithm. If the
QRS during the block changes considerably from the learned normal, the blocked beat may be
incorrectly classified as ventricular, causing false PVC alarms. You should always select a lead where
the bundle branch block beats have an R-wave that is as narrow as possible to minimize incorrect calls.
Ventricular beats should look different from these 'normal beats'. Instead of trying to select two leads
with a narrow R-wave, it may be easier to just select one lead and use single lead arrhythmia
monitoring. Extra vigilance is required by the clinician for this type of patient.
