title: A Unique Ectopic Atrial Rhythm: Where Is the Origin?
abstract: In predicting the origin of focal atrial arrhythmias, a precise analysis of the P-wave morphology in the 12-lead electrocardiogram is essential. In this report, we demonstrate a unique ectopic atrial rhythm and discuss its origin by analyzing the P-wave morphology.
