目的:探讨主动脉窦部室性早搏(简称“室早”)和右心室流出道间隔部室早心电图特征的差别。方法选取12例右心室流出道间隔部室早( A组)心电图作为对照,分析12例主动脉窦部室早( B组)的心电图特征。结果与A组相比,B组V1、V2导联的R波时间指数增大[V1导联:(0.23±0.10) vs.(0.49±0.28);V2导联:(0.24±0.12) vs.(0.57±0.23);P均<0.05]。 V1、V2导联的R/S波幅指数A组小于B组[ V1导联:(0.10±0.02) vs.(0.87±0.55);V2导联:(0.21±0.14) vs.(1.13±1.49),P均<0.05]。 A组胸前导联R波移行在V3导联或其后,B组胸前导联R波移行在V1或V2导联。 A组V1、V2导联的R波移行指数小于B组[V1导联:(0.25±0.15) vs.(1.30±0.68); V2导联:(0.31±0.20) vs.(1.71±1.14), P均<0.05]。结论主动脉窦部室早与右心室流出道间隔部室早在V1、V2导联R波时间指数、R/S波幅指数、胸前导联R波移行位置及移行指数上有明显的差别。

Objective To investigate the difference in ECG characteristics of premature ventri-cular contraction ( PVC) originating separately from aortic sinus cusp ( ASC) and the septum of right ventricular outflow tract ( RVOT).Methods The ECG characteristics of 12 ASC-originated PVC patients( group B) were analyzed and compared with those of another 12 patients with PVC origina-ting from the septum of RVOT(group A).Results The indexes of R-wave duration in lead V1,V2 were significantly lower in group A than those in group B [V1 lead: (0.23 ±0.10) vs.(0.49 ± 0.28);V2 lead:(0.24 ±0.12) vs.(0.57 ±0.23), P<0.05, respectively].The indexes of R/S-wave amplitude in lead V1,V2 were significantly lower in group A than those in group B [V1 lead:(0.10 ±0.02) vs.(0.87 ±0.55); V2 lead: (0.21 ±0.14) vs.(1.13 ±1.49), P <0.05, respectively ] .The R-wave precordial transitional position was located in it or after it in group A while in lead V1 or V2 in group B.The transitional indexes of lead V 1 and V2 were significantly lower in group A than those in group B [V1 lead:(0.25 ±0.15) vs.( 1.30 ±0.68);V2 lead:(0.31 ± 0.20) vs.(1.71 ±1.14), P<0.05, respectively].Conclusion Between ASC-originated PVC and PVC originating from the septum of RVOT , there are significant differences in the indexes of R-wave duration , R/S-wave amplitude , and R-wave precordial transitional position and the transi-tional indexes in lead V 1 , V2 .
