Comparison of Recurrence Rate Based on the Frequency of Preceding Symptoms in Patients With Neurocardiogenic Syncope or Presyncope

Background and Objectives In patients with neurocardiogenic syncope or presyncope, symptoms developed unpredictably and intermittently. The purpose of this study was to determine whether there was any significant difference in the recurrence rate of symptoms during the follow-up period between patients with many episodes of symptoms and those with fewer episodes of symptoms before diagnosis, as well as to assess the clinical significance of previous episodes of symptoms during treatment.
