Complete heart block (CHB) following retrograde left ventricular cathe
terization is uncommon. We report a case of transient CHB in a patient
with severe aortic stenosis and bifascicular block on the baseline su
rface electrocardiogram during retrograde left ventricular catheteriza
tion. The block resolved spontaneously without sequelae. A review of t
he literature using MedLine was performed and recommendations for temp
orary and permanent pacing are outlined. (C) 1994 Wiley-Liss, Inc.
