TI  - Relationship of heart rate turbulence, heart rate variability and the number of 
      ventricular premature beats in patients with mitral valve prolapse and 
      non-significant regurgitation.

AB  - Cardiac arrhythmia is frequently detected in patients with mitral valve prolapse 
      (MVP) and improper autonomic tone is considered the etiology. Heart rate 
      turbulence (HRT) and heart rate variability (HRV) are methods assessed for 
      autonomic dysfunction. To evaluate whether the number of ventricular premature 
      contractions (VPCs) is influenced by HRT or HRV in patients with MVP. Holter 
      monitoring for the number of VPCs and correlation analysis with HRT and HRV was 
      performed. There were 31% and 3% with abnormal turbulence onset (TO) and 
      turbulence slope (TS) values in totally 68 patients. No significant correlation 
      is found between the number of VPCs and HRT, HRV parameters. In analysis the 
      relationship between HRT and HRV parameters, TS has higher correlation with HRV 
      than TO values, particular in time-domain.
