Abstract

Background & Objectives: Dengue mostly spreads in tropical and subtropical climates. Dengue is known to affect various systems. Cardiovascular system is one of them. This study was conducted to study the frequency of Electrocardiographic (ECG) changes in patients with dengue fever and dengue hemorrhagic fever.

Materials and Methods: This study was conducted in kanyakumari government medical college in the department of general medicine. 100 patients were included in the study over a period from September 2017– February 2018 for a period of 6 months. The details of the patient, clinical presentation and examination was noted. ECG was carried out in all patients.

Results: Out of 100 patients, 42 patients had normal ECG. Abnormal ECG findings like tachycardia, bradycardia, bundle branch block, ST depression, 1st degree AV block, ventricular ectopics were noted among the 58 patients. 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 bradycardia and tachycardia
