Abstract

Background: World Health Organization estimates that 50-100 million dengue infections occur every year with 22000 deaths. The increasing magnitude of the problem together with its changing epidemiology is an important public health concern. The aim of this study was to observe the presence of Electrocardiographic changes in patients of dengue infection and to evaluate whether there were any related clinical cardiac manifestations and correlation of cardiac manifestations to warning signs of dengue.

Methods: This study was conducted at tertiary care institute in department of medicine. Data obtained from 74 patients over the period of one year fulfilling inclusion criteria were studied.

Results: 16 patients had no warning signs, 58 patients had warning signs, out of which 39 patients had two or more warning signs, while 19 patients had single warning sign. Most common warning sign in this study was abdominal pain and Vomiting while Hepatomegaly was the least common warning sign. The most common cardiac abnormalities noted were rhythm abnormalities of which the commonest was sinus bradycardia, found in around 56% of the patients. There was statistically significant correlation between cardiac manifestations and all the warning signs except lethargy/restlessness and Hepatomegaly.

Conclusions: The most common cardiac manifestations noted were transient rhythm abnormalities, of which sinus bradycardia was the commonest. There was statistically significant correlation between cardiac manifestations and all the warning signs except lethargy/restlessness and hepatomegaly.  

Keywords: Electrocardiography, dengue infection, cardiac manifestations.
