title: Three origins of focal atrial tachycardia in the lateral mitral isthmus.
abstract: Multiple origins of focal atrial tachycardia (AT) located at the left lateral isthmus is a rare case. We present a case of a 31-year-old female with incessant AT. During radiofrequency ablation, 3 origins of AT located in the lateral mitral ishtmus from a lower to a higher position were identified with changes of the ECG morphology and earliest activation on 3D mapping. Ablation of the AT origins can terminate the tachycardia.
