Myocarditis with sinus exit block: A rare presentation of Plasmodium vivax malaria

Although malaria is caused most commonly by falciparum species, vivax malaria counts the second most common in India. Until recently, severe malaria infection was attributed to falciparum species. Various systemic complications including arrhythmia, heart failure, conduction disturbances, and myocarditis have been typically seen in association with Plasmodium falciparum infections. Nowadays, severe vivax malaria encompasses varied complications including cardiac complication as well. We report a case of sinus exit block due to myocarditis in a 40-year-old male infected with vivax malaria without any cardiovascular risk factors. Recovery was complete with a favorable outcome in this case.
