AB  - Diurnal variations in ventricular tachyarrhythmias (VAs) have been demonstrated 
      in idiopathic arrhythmogenic heart disease. The electrophysiological 
      characteristics of diurnal variations in idiopathic right ventricular outflow 
      tract (RVOT) VA have not previously been elucidated. Sixty-two consecutive 
      patients undergoing catheter ablation for idiopathic RVOT VA (mean age: 
      42.8 +/- 12.3 years, 35 females) were enrolled. The diurnal variation type (group 
      1, n = 36) was defined as those patients who had most ventricular premature 
      contractions (VPCs) during the night hours by preprocedure Holter recordings. 
      Group 2 (n = 26) was defined as those patients who did not have significant VPC 
      variations. The baseline characteristics and electrophysiological properties were 
      collected and analyzed, and the rates of recurrence after catheter ablation were 
      compared between the 2 groups. In this study, heart rate variability analysis 
      demonstrated lower low frequency/high frequency ratios in group 1 than in group 2 
      (3.95 +/- 3.08 vs 6.26 +/- 5.33; P = 0.042). There were no significant differences in 
      baseline characteristics, echocardiography and electrophysiological 
      characteristics between the 2 groups. During a mean follow-up period of 
      13.5 +/- 11.0 months, a total of 16 patients had VA recurrences, including 13 
      patients from group 1 and 3 patients from group 2 (36.1% vs 12.5%, P = 0.039). 
      This study demonstrated the effect of the autonomic nervous system in idiopathic 
      RVOT VAs and that the diurnal variation type leads to a higher recurrence rate 
      after catheter ablation.
