Cholestatic hepatitis after diagnostic ajmaline challenge.

We report a cholestatic hepatitis in an elderly woman after ajmaline challenge during electrophysiological testing for Brugada syndrome. No other medication was reported in the previous 6 months of the onset of jaundice. Liver biopsy showed a cholestatic hepatitis with mild biliary damage. Liver enzymes normalized within 2 weeks as well as jaundice. To the best of our knowledge this is the second case of histologically proved cholestatic hepatitis induced by intravenous ajmaline testing.
