Electrocardiographic artifact due to an arteriovenous fistula

A 78-year-old man who had been undergoing hemodialysis for 5 years presented to our outpatient department because of chest discomfort at rest, which had developed the previous evening. His initial electrocardiogram, in which the left arm electrode happened to be placed near the anastomosis site of an arteriovenous fistula, revealed elevation of the late component of the T-wave and TP segment in leads I and aVL (Figure  1). It also revealed depression of the late component of the T-wave and TP segment in leads III, aVR, aVF, and V1–V6 (Figure 1).
