Background and Objectives: Dengue mostly spreads in tropical climates. Dengue is known to affect various systems, cardiovascular system is one of them. This study was conducted to observe the presence of electrocardiographic (ECG) changes in patients presenting with dengue fever. Materials and Methodology: This study was conducted in KVG medical college in the department of general medicine. Cases were selected after taking into account the inclusion and exclusion criteria from serologically confirmed dengue cases. The details of patient’s clinical presentation and examination was noted. ECG was carried out to all patients Results: Out of 100 patients, 51 patients had normal ECG. Abnormal ECG findings like sinus bradycardia, tachycardia, ST-T changes, Bundle branch block were noted among 49 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 Non-specific ST-T changes. No evidence of myocarditis was seen.
