Ajmaline induced intra-Hisian block.
Ajmaline-induced block within the atrioventricular bundle (intra-Hisian) is rare. We report a 59-year-old male with a left bundle branch block in whom intravenous Ajmaline unmasked a latent conduction abnormality within the atrioventricular bundle. Relevant literature is reviewed.
