| 内容記述 | In sustained ventricular tachycardia(VT), the conductive property of the reentrant circuit was characterized by the use of transient entrainment and related to the ability to interrupt VT in 25 patients. At 1－10 paced cycle lengths, VT was entrained in all patients with rapid pacings but interrupted in 16 patients. As the paced cycle length decreased in 4 or more steps, the conduction time which was measured as the interval between the stimulus and the orthodromically captured electrogram was analyzed in 21 patients. Of these, 14 patients showed a rate depenent prolongation of the conduction time；a decremental conduction, and 7 showed a fixed value. VT with a decremental conduction was interrupted in 78.6% but VT without a decremental conduction was interrupted only in 28.6%. The study was repeated in 7 patients in which VT showed a decremental conduction. VT with same QRS morphology but with different cycle length was induced after procainamide；327±50 msec vs. 412±36 msec (p<0.01), and all of them were interrupted. The conduction time prolonged by 41±16 msec for the mean decrement of the paced cycle length by 50±22 msec before procainamide. After procainamide, a significantly smaller prolongation；17±18 msec was observed for the similar degree of the decrement of the paced cycle length；44±15 msec (p<0.01). The increment of conduction time for the decrement of the paced cycle length would be reflect the conductive property and would be related to the ability to interrupt tachycardia with rapid pacings. With antiarrhythmic drugs, the decrernental property might be attenuated from the slowing of tachycardia rate but the interruption seemed to be facilitated. | |||||
