ABSTRACT

Arrhythmias are seen less in children in comparison to the adult population. The most significant arrhythmias that are seen in children are supraventricular tachycardia. The sudden onset of arrhythmias should alert the physician for differential diagnosis of various reasons including drug intoxications and acute electrolyte abnormalities. A 13-year-old boy presented to the emergency clinic after the administration of anti-flu medications due to his not feeling well, sweating, and abdominal pain, and the ECG (electrocardiography) showed diffuse delayed conductance abnormality. This case report demonstrates an ECG finding that has not been published in the literature and shows a delay in conductance that has not been observed before. The clinical status of this patient is considered to be related to the side effects of the medications (anti-flu medications) that caused the delayed conductance in the whole conductance system of the heart.
