Second Degree Mobitz Type 1 Block in Dengue Haemorrhagic Fever: A Rare Manifestation

Dengue is an arboviral disease caused by a Flavivirus. It is spread by the bite of Aedes aegypti mosquito. Spectrum of this disease ranges from mild self-limiting fever to potentially fatal severe multiorgan dysfunction with shock. Cardiac manifestations of dengue are uncommon but rhythm disturbances in the form of ventricular ectopics and different types of blocks have been reported with dengue haemorrhagic fever in the literature. Here, we present a case report of a young lady who developed 2nd degree Mobitz type I block during the de-fervescence stage of infection.
