Dengue is one of the most important emerging viral diseases globally. The majority of infections follow a relatively benign disease course.  However, a small proportion of patients develop severe clinical manifestations, including bleeding, organ impairment, and endothelial dysfunction, eventually cardiovascular collapse. Evidence is increasing that dengue can also cause myocardial impairment, arrhythmias and, occasionally, fulminant myocarditis. We report a case of ayoung male patient who presented as a prototype case of dengue myocarditis, except for an extremely rare occurrence of a wandering pacemaker which was detected on a routine ECG. This case emphasizes the importance to keep a trained & vigilant eye, even in the face of what appears routine.
