A 24h ambulato ry elettrocardiogram (Holier) was Performed to hudge the therapeutic efficacy before and after themedicatiou in all the 33 petients who took 300 mg/d, 450 mg/d, 600 mg/d dl-THP tblet in turn perweek. Total effective rate is 66. 7% ; more than 90% SVPBS disappear .in 18. 2% ; and more than75% SVPB. disappear in 48. 5%. Otherwise total affective rate is 13. 3% in placebo group.
