摘要
目的研究导管射频消融术（ＲＦＣＡ）对ＱＴ、ＪＴ离散度（ＱＴｄ、ＪＴｄ）的影响。方法测量６２例阵发性室上性心动过速和４例特发性室速患者ＲＦＣＡ术前、术后的ＱＴｄ、ＪＴｄ。结果所有患者术前、术后ＱＴｄ、ＪＴｄ无显著差异（Ｐ均＞０．０５），三组不同电生理机制的室上速患者之间术后ＱＴｄ、ＪＴｄ差异无显著性（Ｐ均＞０．０５）。结论ＰＦＣＡ不影响正常心室肌复极离散度。
Objective The purpose of this study was to investigate the influence of radiofrequency catheter ablation(RFCA) on the dispersions of QT and JT interval.Method QT and JT interval dispersions were measured in 62 patients with paraxyomal subraventricular tachycardia and 4 patients with idiopathic ventricular tachycardia before and after RFCA.Results Dispersions of QT and JT interval had no significant difference before and after RFCA in all patients( P <0 05).The differences of QTd and JTd were not remarkedly among the three groups which had different electrophysiology mechanism in patients with supraventricular tachycardia after RFCA( P <0 05).Conclusion RFCA may not effect the dispersion of ventricular perplarization in normal heart.
