Case ReportsCase of Wenckebach-type atrioventricular block caused by administration of indigo carmine.
We report a case of first-degree atrioventricular (A-V) block progressing to second-degree (Wenckebach-type) A-V block after administration of indigo carmine in a patient undergoing hysterectomy under general anesthesia. We believe that the onset of Wenckebach-type A-V block may have been induced by one or more of three factors: 1) preoperative first-degree A-V block, 2) the anesthetics used (propofol and remifentanil), and 3) administration of indigo carmine.
