为了评价射频消融（ＲＦＡ）对心室功能的影响，应用核素心室显像（ＲＮＶ）测定了３８例［３５例为预激综合征（Ｗ－Ｐ－Ｗ）合并室上性心动过速（ＳＶＴ），３例为合并定性心动过速（ＶＴ）］患者ＲＦＡ前后以及２０例正常对照者的心室功能，半自动计算左心室射血分数（ＬＶＥＦ）、右心室射血分数（ＲＶＥＦ）、１／３ＬＶＥＦ、左室高峰充盈率（ＬＶ－ＰＦＲ）、右室高峰充盈率（ＲＶ－ＰＦＲ）．结果提示：窦性心律时．对照组与病人组ＲＦＡ前、后心功能差异无显著性．而１０例Ｗ－Ｐ－Ｗ患者经食道诱发ＳＶＴ以及３例患者经右心导管诱发ＶＴ时，心功能明显下降，与窦性心律时心功能结果比较Ｐ＜０．０１，ＲＦＡ术后又明显改善．由此可见，室上性心动过速或室性心动过速时发生的心功能失调是可逆的．证实核素心室显像评价快速性心律失常患者ＲＦＡ术前、术后心室功能是一种无创伤性的可靠方法．
To evaluate the effect of radiofrequency ablation (RFA) on ventricular function, radionuclide ventricular imaging (RNV) was used in 38 patients (35 patients with pre-excitation syndrome (W-P-W) with supraventricular tachycardia ) And ventricular function in 20 normal controls before and after RFA in 3 patients with combined qualitative tachycardia (VT). The left ventricular ejection fraction (LVEF), right ventricular ejection fraction (RVEF) and 1 / 3LVEF , Left ventricular peak filling rate (LV-PFR) and right ventricular peak filling rate (RV-PFR). The results suggest that: sinus rhythm. There was no significant difference in cardiac function before and after RFA between the control group and the patient group. However, cardiac function was significantly decreased in 10 W-P-W patients with SVT induced by the esophagus and 3 patients with VT induced by right cardiac catheterization, P <0.01 compared with those in sinus rhythm improve. Thus, supraventricular tachycardia or ventricular tachycardia occurs when the heart dysfunction is reversible. Confirmed nuclide ventricular imaging evaluation of patients with tachyarrhythmia Before and after RFA, ventricular function is a non-invasive and reliable method.
