[Electrocardiographic changes in leptospirosis].

The study involved 239 ECGs recorded in acute period of various leptospirosis forms. In 86.2% of cases there were changes evidencing impairment of neuromuscular system and atrial (76.6%) or ventricular (61.9%) conduction. The above cardiac manifestations arise early, have peculiar characteristic features. The discussion covers their patho- and morphogenesis, frequency of detection, necessary time-course ECG control over leptospirosis patients and convalescents.
