Dengue fever (DF) is a common mosquito-borne viral illness, with various cardiovascular implications, including electrocardiographic abnormalities, due to profound myocardial involvement (myocarditis) by the dengue virus. Here, we are describing an untraditional presentation of DF, in which a young male encountered with cardiac rhythm abnormalities without fever, thrombocytopenia, or capillary leakage. The patient had symptomatic hypotension, and his electrocardiogram (ECG) demonstrated alternative patterns of ventricular bigeminy and trigeminy. Serum electrolytes, total leukocyte counts, and renal function tests were normal, but cardiac biomarkers were elevated in this patient. Two-dimensional echocardiography demonstrated global left ventricular wall hypokinesia with an ejection fraction of 53%, but the coronary angiography indicated no vascular thrombus or occlusion. Subsequent evaluation found that the dengue IgM antibody by enzyme-linked immunosorbent assay was positive in this patient. He was managed conservatively for this and had a splendid recovery in the form of normal ECG at the time of discharge and echocardiography on follow-up. The case delineates a rare and challenging presentation of cardiac involvement in DF.
