**7.3.4 Yersinia myocarditis**

Myocarditis sometimes occurs as a complication of Yersinia. Clinical evidence of Campylobacter-associated myocarditis described in association with *Campylobacter* spp. enteritis (Kotilainen et al., 2006). Mild, self-limited myocarditis accompanies 10 percent of cases of Yersinia induced arthritis and can occur independently. Typical manifestations include cardiac murmurs and transient electrocardiographic abnormalities, such as prolongation of the PR interval and nonspecific ST-segment and T wave changes. The syndrome of Yersinia-induced arthritis and carditis can be confused with acute rheumatic fever.
