TI  - Characteristics of ventricular premature contractions and their clinical course.
PG  - 190-8
AB  - One hundred patients with frequent (> 1,000 beats/day) ventricular premature 
      contractions (VPCs) were followed for 4 years. All of the patients, except those 
      with non-cardiac death (n = 8), were classified into 3 groups based on their 
      outcome. Group A consisted of 29 patients with idiopathic VPCs who survived the 
      study period. Group B consisted of 49 patients with underlying diseases who 
      survived the study period. Group C consisted of 14 patients who suffered cardiac 
      death. There was no significant difference in the daily number of VPCs. However, 
      groups B and C had more patients with Lown grade 4a or 4b VPCs than group A. The 
      mean coupling interval was significantly longer in group C than in group A, and 
      the standard deviation of the coupling interval was significantly larger in group 
      C than in group A. Forty patients underwent serial Holter monitorings to assess 
      changes in the number of VPCs. VPCs spontaneously decreased in 13 patients, while 
      the other 27 patients continued to have frequent VPCs. Most of these 13 patients 
      were classified as Lown grade 2. The results suggest that in patients with 
      frequent VPCs, longer and more varied coupling intervals may predict a poor 
      prognosis, and Lown grade 2 may predict a spontaneous regression.
