Study phase:

探索性研究/预试验

Pilot clinical trial

研究目的:

(1)研发基于128通道体表心电图的无创性三维体表心电标测技术平台; (2)基于随机对照试验,比较新建三维体表心电标测技术平台与常规12导联体表心电图的定位准确性; (3)基于随机对照试验,通过与射频消融治疗室性心律失常的常规方案比较,评价无创三维体表心电标测辅助下射频消融治疗室性心律失常的疗效及安全性,并评估其临床应用价值及探索临床应用路径方案。

Objectives of Study:

1. To develop a new system of noninvasive three-dimensional electrocardiographic mapping based on 128 channel body surface electrocardiogram; 2. To compare the mapping accuracy between the ECGI system and conventional 12-lead electrocardiogram through a randomized controlled trial; 3. To assess the efficacy and safety of catheter ablation for ventricular arrhythmias guided by noninvasive three-dimensional electrocardiographic mapping and to compare that with conventional ablation method through a randomized controlled trial. The potential clinical value and clinical application pathway of ECGI were also investigated.

Description for medicine or protocol of treatment in detail:

纳入标准:

①室性早搏和/或非持续性室性心动过速患者; ②年龄在18周岁至80周岁; ③室早/室速症状明显但药物治疗无效、不能耐受或不愿意接受抗心律失常药物者; ④无明显症状但因心动过速导致左心室功能下降或出现心动过速心肌病; ⑤24小时动态心电图提示室性早搏大于10000次/24h或室性早搏负荷大于10%; ⑥同意接受该项试验研究并且签署知情同意书.

Inclusion criteria

1. Patients diagnosed with premature ventricular contractions (PVCs) and ventricular tachycardia (VT); 2. Patients aged between 18 and 80 years; 3. Patients with obvious symptoms of PVCs/VT but cannot be relieved or tolerate antiarrhythmic medicine; 4. Impaired left ventricular function or tachycardia-induced cardiomyopathy due to asymptomatic PVCs/VT; 5. Frequent monomorphic PVCs/VT (>10000 per 24 h or burden >10%); 6. Informed consent can be obtained.
