Design Prospective, observational study. Setting Surgical ICU in a university hospital. Patients Fourteen patients with fungemia and 14 control patients. Measurements and Main Results Serum samples from all patients were assayed in an in vitro sinus node preparation. Serum samples from 11 (78%) of the 14 fungemic patients caused a decrease in sinus node activity, while serum samples from only one (7%) of 14 control patients caused slowing of the sinus node. Conclusions Serum from many patients with fungemia causes slowing of an in vitro sinus node preparation. This in vitro finding may explain bradyarrhythmias seen clinically in the setting of fungemia. © Williams & Wilkins 1992. All Rights Reserved.
