“…In addition, in the Chinese series, no case of syncope or sudden death has been observed before or after ablation of the arrhythmias (10,11). Therefore, we do recommend patient reassurance policy in asymptomatic or mildly symptomatic patients (i.e., palpitations) displaying these arrhythmias after extensive work-up including repeat 12 leads ECG Holter and maybe pharmacologic drug testing as recommended by the Bordeaux group (12). In contrast, if such arrhythmias are documented in a patient who suffered one or more "true syncopal" events, extensive work-up should be performed with high suspicion that the syncope might be related to aborted malignant tachyarrhythmias.…”
