Summary

We studied the cardiac conduction system in a case of Hurler syndrome. There was dense fibrosis of the supporting matrix of the sinus node and accumulation of mucopolysaccharide in the nodal cells. The bundle branches showed prominent hydropic degeneration, being encased and punctuated by dense fibrous tissue. These changes in the conduction system may predispose to the development of arrhythmias, accounting for the sudden deaths in Hurler syndrome.
