Electrocardiographic and echocardiographic manifestations of cardiac involvement in leptospirosis.

摘要

Cardiac involvement is known to occur in leptospirosis, however, data on the significance of electrocardiographic and echocardiographic findings is very limited.Electrocardiographic and echocardiographic changes were studied in serologically confirmed patients with leptospirosis.Of 22 patients, 45% (10) had cardiac symptoms; 59% (13) had abnormalities on the ECG; 90% (9/10) of patients with cardiac symptoms had at least one electrocardiographic abnormality. Echocardiographic abnormalities were seen in 41% (9). Clinical and echocardiographic evidence of myocarditis was seen in two patients, but left ventricular function was preserved.Echocardiographic changes may be useful in identifying patients with myocarditis in leptospirosis, especially in symptomatic patients.
