ECG CHANGES IN DENGUE FEVER

Abstract

Background: Dengue is one of the most important viral diseases globally and a majority of symptomatic infections result in a benign course. However, a small number of patients develop severe manifestations, including myocardial impairment, arrhythmias, and fulminant myocarditis. Dengue is known to affect various systems. The cardiovascular system is one of them. This study was conducted to observe the presence of electrocardiographic (ECG) changes in patients presenting with dengue fever. Material and method: This was a cross sectional analytical study conducted at Jhalawar medical college and hospital, Jhalawar, Rajasthan. 146 cases were selected after taking into account the inclusion and exclusion criteria from serologically confirmed dengue cases. The details of the patient's clinical presentation and examination was noted.ECG was carried out to all patients. Results: Out of 146 patients,58 patients had normal ECG. Abnormal ECG findings like sinus bradycardia ,tachycardia ,ST-T changes,bundle branch block were noted among 88 patients. Conclusion: ECG changes can occur in dengue infection, most common finding were sinus bradycardia. ECG abnormalities were common but all the ECG changes were reversible. There was no evidence of myocarditis in any of the patients
