The long-term reproducibility and significance of inducible @entity943 were assessed in 21 survivors of a @entity583 . Programmed ventricular stimulation performed a mean of 12 +/- 2 days (range 8 to 18) after @entity1188 provoked @entity2224 in 2 @entity1 , sustained monomorphic @entity1165 in 8 and nonsustained @entity1165 in 11. @entity1 were restudied using the same protocol a mean of 8 +/- 2 months (range 4 to 11) after @entity1188 . All @entity1 underwent programmed ventricular stimulation studies in the absence of antiarrhythmic drug treatment. @entity1165 could be reinitiated in 16 @entity1 (76%): @entity2224 in 2, sustained @entity1165 in 5 (monomorphic in 4) and nonsustained @entity1165 in 9. A preponderance of inferior @entity1188 was observed among @entity1 with reinducible @entity591 (9 of 16 @entity1 versus 0 of 5 with noninducible @entity591 ) (p less than 0.05). No significant difference existed between @entity1 with and without reinducible @entity943 with respect to severity of @entity453 , degree of @entity1002 , occurrence of @entity2224 in the acute phase of @entity1188 and @entity943 detected by 24 hour ambulatory electrocardiographic (Holter) monitoring. There was no significant difference between @entity1 with and without a positive late study in stimulation thresholds, ventricular refractory periods, time interval between initial and repeat testing and use of beta-adrenergic blocking agents. During a mean follow-up period of 17 months (range 10 to 23) one @entity1 with inducible sustained monomorphic @entity1165 at both studies died suddenly. The remaining @entity1 have survived follow-up without experiencing an arrhythmic event.(ABSTRACT TRUNCATED AT 250 WORDS)
