在致心律失常性右心室发育不良(ARVD)患者中的室性心动过速(VT)多为折返机制,关于其射频消融较少报告,现报道2例应用拖带标测技术指导消融ARVD合并的右心室流入道VT。 资料和方法 例1男性22岁,例2女性37岁,分别以发作性心悸2年、1年,近期加重入院。2例多次12导联体表心电图均表现为反复发作的持续性VT,例1、例2分别显示2种、1种形态VT。2例患者近期VT多次发作,发作时多种抗心律失常药物治疗无效,均需直流电同步电转复。服用胺碘
In patients with arrhythmogenic right ventricular dysplasia (ARVD) mostly ventricular tachyarrhythmias (VT) are the mechanism of reentry, radiofrequency ablation is less reported, it was reported in 2 cases of the use of tow mapping technique to guide the ablation of ARVD merger Right ventricular inflow tract VT. Materials and Methods Example 1 Male 22 years old, 2 cases of female 37 years old, respectively, onset of heart palpitations 2 years, 1 year, recent hospital admission. 2 cases of multiple lead 12-lead surface ECG showed recurrent persistent VT, cases 1 and 2 showed two kinds of morphological VT. Two patients with recent VT multiple attacks, seizures, a variety of anti-arrhythmic drugs ineffective, are required DC synchronous electrical recovery. Take amine iodine
