ECG Manifestations in Dengue Infection

BACKGROUND AND OBJECTIVES Dengue is endemic in the tropics, and complications involving organ systems are seen with varying incidence. The present study was conducted to find out the proportion of dengue fever cases with ECG changes. MATERIALS AND METHODS This is a descriptive study.232 successive dengue fever cases were selected for the study. Patients with Dengue Hemorrhagic fever underwent radiological examination in form of chest radiograph and ultrasound abdomen. ECG was carried out in all patients. Appropriate investigations were done. RESULTS Out of 232 patients, 122 (52.58 %) suffered from Dengue Fever and 110 (47.42 %) had Dengue Hemorrhagic Fever. Overall 156 patients had normal ECG. Abnormal ECG findings like tachycardia, bradycardia, supraventricular tachycardia, left bundle branch block, ST depression, poor progression of R wave were noted. There was no significant relationship of ECG findings with the disease. CONCLUSION ECG changes can occur in dengue infection with or without cardiac symptoms. Commonly noted findings were ST depression and bradycardia.
