AV Fistula / Graft Artifact on ECG This ekg was sent to me by a friend. Pt sent from dialysis clinic for chest pain, but after several attempts and two machines, they still couldn’t get an ekg without artifact. The artifact is cause by a limb lead being on the patients AV fistula or graft. Eric Abrams, MD @eabramsMD #AVFistula #Graft #Artifact #ECG #EKG #Electrocardiogram #cardiology #clinical
