BRADYCARDIA-AN ALARMING SIGN IN DENGUE FEVER

Abstract

Dengue Fever is one of the most common vector borne disease which is caused by bite of Aedes aegypti in Tropical parts of world. Bleeding manifestations are most common signs due to Thrombocytopenia. Relative Bradycardia which is becoming one of the cause of mortality in Dengue Fever. This study aims to observe, changes in Heart rate in Dengue Fever. Materials and methods: This was an observational study done at Narayana medical college and hospital, Nellore, from June 2021 to October 2022 on 150 patients satisfying inclusion and exclusion criteria, demographic data and clinical features and laboratory evaluation was done for patients in the study vitals signs (pulse/heart rate, Blood pressure, respiratory rate, temperature) was noted for all patients. Results: Out of 150 patients, 43.3% have relative bradycardia and 30% patients have absolute bradycardia with ECG showing sinus bradycardia in 28% of patients. Conclusion: Relative bradycardia in dengue fever patients is present in association with thrombocytopenia and is important contributing factor to mortality in patients with dengue fever.
