Background: Electrocardiographic (ECG)changes have been observed in leptospirosis. The prevalence of ECG
alterations may reach 80%. Despite of this finding,few studies have been conducted to assess ECGpatterns in only
hospitalized leptospirosis patients in Indonesia.
Objective: To reveal the prevalence and type of ECGalterations in hospitalizedleptospirosisand its association with
disease severity.
Methods: This was a cross-sectional study using medical record data. Patients hospitalized in Dr. Sardjito Hospital
(January 2003 - December 2007) with leptospirosis (lCDXA27.9) were enrolled. Electrocardiogramstaken in 24
hours of admission were evaluated. Disease severity was determined based on clinical and laboratory findings.
Association between disease severity with ECGrecordings were performed using Kruskal-Wallisand Chi square
test. P value < 0.05 was significant.
Results: Sixtysamples were analyzed.The prevalence of alterationof ECGrecordingswas 66.7%. Sinustachycardia
was the most frequent (36.7 %). The most common arrhythmia was atrial fibrillation(10 %). Other abnormalities
were alterationof ventricularrepolarization(8.3%1.extrasystoles (6.6%) and disorderof conduction (4.9%). Although
not significant, those with atrial fibrillationtended to have the worst clinicaland laboratory findings.
Conclusions: The prevalenceof alterationof ECGrecordingsin hospitalizedleptospirosiswas 66.7 %. Atrialfibrillation
was the most frequent arrhythmia, and patients with this arrhythmia were likelyto have the most severe disease.
