title: Sinus arrest developed during gastric cancer operation in a progressive systemic sclerosis patient.
abstract: We report a case of progressive systemic sclerosis (PSS) who suddenly developed sinus arrest during an operation for gastric cancer under general anesthesia. No abnormalities in her cardiac, respiratory or renal functions had been detected before surgery. The cardiac functions evaluated by echocardiogram before and after pacemaking eliminated heart muscular involvement. We speculated that the operation stress induced by general anesthesia altered the asymptomatic fibrotic sinus into apparent sinus dysfunction. Care should be taken in general anesthesia for scleroderma patients who are free from detectable cardiac manifestations.
