Abstract

A routine screening electrocardiogram on a amateur pilot revealed what was initially thought to be an episode of atrial tachycardia. Minutes later, the record was within normal limits. The initial reading contained an artifact. A clear explanation of the distribution (within the 12 leads) of the artifact is given. The case illustrates that if an artifact is produced at any 1 of the 3 limb lead connections, it is possible to predict the size of the artifact in all 12 simultaneously recorded leads.
