title: Electrocardiographic abnormalities in leptospirosis.
abstract: Electrocardiographic abnormalities occurred in 46 per cent of cases uith leptospirosis. Although the individual changes noted do not appear to be of importance, they indicate that sub-clinical cardiac involvement does occur in a significant proportion of the patients. The abnormalities observed include disorders in cardiac rhythm and changes in the P-QRS-T complexes, probably resulting from direct myocardial involvement or from a  changing milieu interior. While serial tracings are indicated in patients with acute renal failure of the oliguric variety, repeated tracings may detect more definitely changing patterns which indicate the presence of cardiac involvement in patients with other presentations of the disease.
