title: [Asymptomatic myocarditis after infection of the upper respiratory tract].
abstract: METHODS
  A 20-year-old patient was hospitalized with persistent high fever after tonsillitis and swelling of the talocalcanean joint.
  
  
  METHODS
  The ECG showed a partial right bundle branch block pattern and pathological T inversions on the left precordial leads. Cardiac Troponin I levels were slightly elevated and echocardiography revealed a dyscinetic area at the right ventricular apex. The anti-streptolysin titer was elevated.
  
  
  METHODS
  Post-streptococcal rheumatic myocarditis. THERAPY AND FOLLOW-UP: Antibiotic therapy for 2 weeks. The patient showed subjective full recovery after 6 weeks. The anti-streptolysin titer further increases. Nuclear spin tomography of the heart reveal postinflammatory alterations at the apex of the right ventricle.
  
  
  CONCLUSIONS
  Rheumatoid fever is a rare diagnosis in developed countries. This case, however, illustrates that the true prevalence of rheumatoid carditis might be underestimated in the presence of only minimal heart-and joint-specific symptoms.
