Traumatic sinus node dysfunction.

Abstract

A 50-year-old man exhibited sinus node dysfunction following non-penetrating chest trauma. Transiently elevated cardiac isoenzymes, together with normal past electrocardiograms, support the contention that the blunt chest trauma was responsible for the sinus node dysfunction. This case suggests that this condition may occur more frequently than expected and remain unrecognized. Temporary and subsequent permanent pacing may be necessary. Also emphasized is the potential for liability issues.
