Key result
Electrophysiological study and catheter ablation revealed focal atrial tachycardia originating from the left atrial roof in a 55-year-old man whose surface ECG mimicked atypical atrial flutter.
Case Report (n=1)
Focal atrial tachycardia originating from the left atrial roof can mimic atypical atrial flutter on a surface ECG, highlighting the importance of electrophysiological studies for accurate diagnosis.

EP study essential to distinguish roof-origin focal AT from atypical flutter on ECG; leaves open validation in larger cohorts.
Goya et al. (2000) conducted a case report in Focal atrial tachycardia mimicking atypical atrial flutter (n=1). Electrophysiological study and catheter ablation was evaluated. Electrophysiological study and catheter ablation revealed focal atrial tachycardia originating from the left atrial roof in a 55-year-old man whose surface ECG mimicked atypical atrial flutter.
