Abstract :

Dengue is an acute feile viral disease and is one of the most common arboviral mediated outeaks reported with increased prevalence and with considerable morbidity and mortality. The present study aimed to define relative Bradycardia as a clinical sign and characteristic feature of Dengue fever. A total of 106 cases suspected of dengue were reported from July 2016 to September 2016. Out of which 60 cases were serologically positive for dengue infection. Demographic profile, clinical manifestation and laboratory parameters were noted. Of 60 serologically positive cases, majority were males (56.6%). Fever was the major symptom (100%) followed by headache (96.6%), myalgia (91.6%), retroorbital pain (78.3%), rash (48.3 %), abdominal pain (65%), Nausea–vomiting (88.3%), pleural effusion (28.3%) and petechiae (35%). Clinical Spectrum of cases includes 36.6 % cases of Dengue Fever, 56.6 % cases of DHF and 6.66% cases of DSS. In our study 80 % cases had thrombocytopenia and 20% cases had normal platelet counts. Pulse rate distribution showed 26.6% with adycardia, 55 % with relative adycardia, and 13.3 % with tachycardia and ECG changes showed 38.3 % with sinus adycardia, 48.3 % with normal sinus rhythm, and 13.3 % with sinus tachycardia. Hence, awareness of adycardia as a clinical finding, can help in the early recognition of dengue complications and reduction of death associated with dengue virus infection.
