目的 目的：评价心电图V1导联R波变化在经皮二尖瓣球囊成形术(PBMV)治疗效果的价值。
方法：观察了100例PBMV风湿性心脏病二尖瓣狭窄病人手术前后及随访26.5±10.4个月的心电图变化。
结果：V1导联R波的高度术前、术后及随访时分别为1.36±0.14 mV、1.12±0.10 mV和1.06±0.08 mV(P<0.01,术前与术后及随访相比)；RV1+SV5分别为1.61±0.16 mV、1.32±0.11 mV和1.21±0.10 mV(P<0.01,术前与术后及随访比较)；V1导联R/s分别为3.65±0.26 mV、3.23±0.18 mV和2.81±0.11 mV(P>0.05,术前与术后比较；P<0.05,术前与术后随访比较)。心电轴分别为86.71±20.5、82.60±18.5和80.44±22.5(P>0.05,术前与术后比较，P<0.05,术前与随访比较)。肺动脉收缩压术前、术后及随访分别为6.93±1.25 kPa、4.11±0.76 kPa和3.28±0.63 kPa(P<0.01,术前与术后及随访比较)；肺动脉平均压分别为4.11±0.76 kPa、3.24±0.54 kPa和2.86±0.66 kPa(P<0.01,术前与术后及随访比较)。术后平均肺动脉压下降与V1导联R波下降，RV1±SV5下降及V1导联R/s下降呈正相关，相关系数分别为0.66、0.61和0.46(P均<0.01),随访平均肺动脉压下降与V1导联R波降低，RV1±SV5减小及V1导联R/s降低呈正相关，相关系数分别为0.74、0.70和0.48(P均<0.01)。

结论：心电图V1导联R波的变化与肺动脉压力变化相一致，观察心电图V1导联R波的变化是评价及随访PBMV疗效的简便有效的手段。

Objective: To evaluate the change of R wave (in lead V1 of ECG) in the curative effect of percutaneous balloon mitral valvuloplasty (PBMV).

Methods: The electrocardiography were performed before and after PBMV as well as in a 26.5±10.4 months follow-up (FU) in 100 patients with rheumatic mitral stenosis.
Results: The R wave height in lead V1 was 1.36±0.14 mV, 1.12±0.10 mV and 1.06±0.08 mV at pre-PBMV, post-PBMV and FU (p<0.01 pre-PBMV vs. post-PBMV and FU), respectively. The amplitude of RV1+SV5 was 1.61±0.16 mV, 1.32±0.11 mV and 1.21±0.10 mV at pre-PBMV, post-PBMV and FU (p<0.01 pre-PBMV vs. post-PBMV and FU), respectively. The ratio between R wave and S wave in lead V1 (V1R/s) was 3.65±0.26, 3.23±0.18 and 2.81±0.11 at pre-PBMV, post-PBMV and FU (p>0.05, pre-PBMV vs. post-PBMV; p<0.05 pre-PBMV vs. FU), respectively. The systolic pulmonary artery pressure (SPAP) was 6.93±1.25 kPa, 4.11±0.76 kPa and 3.28±0.63 kPa at pre-PBMV, post-PBMV and FU (p<0.01 pre-PBMV vs. post-PBMV and FU), respectively; the mean pulmonary artery pressure (MPAP) was 4.11±0.76 kPa, 3.24±0.54 kPa and 2.86±0.66 kPa at pre-PBMV, post-PBMV and FU (p<0.01, pre-PBMV vs. post-PBMV and FU), respectively; the decrease of MPAP after PBMV was positively related with the decrease of R wave height in lead V1 and ratio between R wave and S wave in lead V1 and amplitude of RV1+SV5 after PBMV as well as at FU, the relative coefficient was 0.66, 0.61 and 0.46 after PBMV (p<0.01) and 0.74, 0.70, 0.48 at FU (p<0.01), respectively.
Conclusion: The R wave height in lead V1 is affected by the pulmonary artery pressure obviously. It is concluded that the change of R wave in lead V1 is a simple and useful tool for evaluation of PBMV effect., http://www.100md.com
