title: Macroreentrant atrial tachycardia with an isolated pathway mimicking focal activation on three-dimensional electroanatomical mapping.
abstract: A 76-year-old man with two different sustained atrial arrhythmias that occurred after coronary artery bypass grafting underwent electrophysiological studies. Macroreentrant atrial tachycardias were detected with an isolated slow pathway mimicking focal activation on three-dimensional electroanatomical mapping. The slow conduction pathway in the right atrial free wall was assumed to represent tissue damaged by right atrial cannulation during previous coronary artery bypass grafting.
