摘要
本文报道采用心电图及心向量图对经皮气囊二尖瓣成形术治疗风湿性二次瓣狭窄效果进行评价,结果与临床随访及血流动力学改变呈一致,认为是简单可靠的无创性评价指标。
The electrocardiography(ECG) and vectorcardiography (VCG) were performed pre- and post-percutaneous balloon mitral valvuloplasty(PBMV) as well as a 20.5±15.0 months of follow-up (Fu) period in 66 patients with rheumatic mitral stenosis. The P wave height in lead Ⅱ was 2.2±0.6, 1.6±0.7 and l.5±0.7mm pre-and post-PBMV and Fa (P<0.001 pre-vs post- and Fu), respectively. The Ptfv, was -0.09±0.07,- 0.04±0.04 . and -0.05 ± 0,05mm pre- and post-PBMV and Fu (P<0.001 pre- vs post-and Fu). The QRS axis was 88.7±21.6, 81.3 ± 18.9 and 78.7 ±28.6 (P>0.05 pre- vs post-, P<0.05 pre- vs Fu). The amplitude of Rv1+Sv5 Was 0.8±0.6, 0.7 ±0.5 and 0.6 ± 0.4mV (P>0.05 pre- vs post-, P<0.05 pre- vs Fu). Pre- and post-PBMV and Fu magnitude of maximum P vector in the horizontal plane of VCG Was 0.18±0.05, 0.15±0.04 and 0.14±0.06mV (P<0.001 pre- vs pest- and Fu). The QRS loop distributed to the Ⅱ right anterior guadrant of the horizontal plane (of VCG) amounted to 6.4±9.7%, 5.3±9.9% and 3.5±6.5% in area (P>0.05 pre- vs post- P<0.05 pre-vs Fu). These results were comparable with those of the clinical and hemodynamic results. Thus, the ECG and VCG are simple and useful tools for evaluating the PBMV effect.
