[Cardiac manifestations in leptospirosis. Apropos of 15 cases observed in New Caledonia].

The authors report the cardiovascular manifestations observed in 15 cases of severe leptospirosis in New Caledonia. Cardiovascular collapse is frequent. Electrocardiographic alterations consist mainly of arrhythmia secondary to atrial fibrillation and repolarisation disorders. A picture of pseudo-pericarditis has also been observed. These cardiac manifestations represent a factor of gravity when associated with multi-visceral manifestations which control the prognosis.
