A teenage girl presented to the Emergency Department (ED) with chest pain and shortness of breath. An electrocardiogram (ECG) showed sinus bradycardia with uniform asynchronous spikes. Her history was significant for gastroparesis status post gastric pacemaker implantation, with the cause of her asynchronous spikes being the electrical activity of her gastric pacemaker. ECG artifact secondary to a gastric pacemaker has rarely been described in the literature. Here, we present the first case of ECG artifact due to gastric pacemaker electrical activity in a pediatric patient.
