Introduction: Electrocardiographic abnormalities were seen in dengue hemorrhagic fever in approximately 30–75% of cases. They are mostly sinus bradycardia and conduction defects. The most common cardiac arrhythmia in practice is supraventricular tachycardia atrial fibrillation (AF). It is mostly seen in structural heart disease. Supraventricular arrhythmia is very rare in dengue fever.
Methods: We present a case of supraventricular tachycardia AF caused by dengue hemorrhagic fever.
Results: Patients with dengue fever need very close electrocardiographic monitoring. All the laboratory results were found to be normal.
Conclusion: Dengue prevalence is high in India. Physicians should be aware.
