Key result
Noncontact mapping successfully identified focal activity within the left upper pulmonary vein ostium in a 57-year-old man whose tachycardia was misclassified as atypical atrial flutter by standard ECG.
Case Report (n=1)
Noncontact mapping systems can successfully identify and guide ablation of focal atrial tachycardias that mimic atypical atrial flutter on standard ECG.

ECG misclassification of focal tachycardias as atypical flutter may occur; challenges conventional criteria and leaves open validation of noncontact mapping utility.
Ouali et al. (2003) conducted a case report in Focal atrial tachycardia (n=1). Noncontact mapping system was evaluated on Identification of focal activity. Noncontact mapping successfully identified focal activity within the left upper pulmonary vein ostium in a 57-year-old man whose tachycardia was misclassified as atypical atrial flutter by standard ECG.
