Abstract

Scrub typhus is an acute febrile disease transmitted via bites from mite larvae (chigger) infected with Orientia tsutsugamushi. Arrhythmias, ischaemic changes and QT prolongation are some of the observed ECG abnormalities. The patient being reported presented with angina and was found to have sinus bradycardia with ST elevation in inferior leads and T wave inversion in lateral leads. His coronary angiography was normal. Further evaluation leads to the diagnosis of scrub typhus infection. Following doxycycline therapy, his ECG became normal. Afebrile scrub typhus infection with cardiac manifestation is an uncommon scenario.
