摘要 应用计算机-核素心室造影对20例病态窦房结综合征(SSS)患者分别于植入生理性AAI和非生理性VVI起搏器前后进行了时相分析(PA)、等相位电影、心功能参数的测定和对比研究。结果表明:AAI起搏不仅保持正常的心室激动顺序(VAS)、而且增加心室收缩的同步性(VSS),从而左室收缩功能(LVSF)和舒张功能(LVDF)亦有相应提高;VVI起搏后VAS异常,VSS和LVSF降低,但LVDF有代偿性增加。提示:VAS和VSS是影响LVSF和LVDF的重要因素。 Thephaseanalysis(PA),iso-phasecineandtheventricularperfomancein20patientswithsicksinussyndrom(SSS)beforeandafterimplantationofphysiologic-AAIandnonphysiologic-VVIpacemak-erswerecomparativelystudiedbycomputerizedequilibriumradionuclideangiography(ERNA).Theresultsshowedthatphysiologic-AAIpacingnotonlymaintainedthenormalventricularactivationsequence(VAS),butalsostrengthenedtheventricularsystolicsynchrony(VSS)associatedwitharelativeincreaseinleftven-tricularsystolicfunction(LVSF)andleftventricuardiastolicfunction(LVDF).NonphysiologicVVIpacinginducedanabnormalVASandthedecreasesinVSSandLVSF,butLVDFrelativelyincreased.TheresultsindicatethatVASandVSSasimportantfactorsefectingLVSFandLVDF,maysignificantlydeterminethehemodynamicinsultofVVIandAAIpacing.
