Radiofrequency catheter ablation is currently considered as the therapeutic option of choice in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and recurrent ventricular tachycardia (VT).
This study intended to assess the long-term outcome of catheter ablation in patients with ARVC and electrical storm. The specific objective was to assess the relationship between precordial QRS amplitude ratio and outcome of catheter ablation in these patients.
Twenty-eight patients (19 men, age 52.3±14.2years) underwent 48 catheter ablation procedures (range 1-6, six epicardial). During a mean follow-up of 18.7±15.1months, 13 patients (46.5%) experienced VT recurrence. Age >50years and ∑QRSmvV1-V3/∑QRSmvV1-V6≤0.48 but not right ventricular size and acute ablation outcome were associated with VT recurrence during the follow up.
Age >50years and ∑QRSmvV1-V3/∑QRSmvV1-V6≤0.48 predict recurrence of VT after successful radiofrequency catheter ablation of VT in patients with ARVC and electrical storm.
射频导管消融目前被认为是致心律失常性右室心肌病（ARVC）和复发性室性心动过速（VT）患者的首选治疗方法。
本研究旨在评估ARVC和电风暴患者导管消融的长期结果。具体目标是评估这些患者胸前导联QRS波振幅比与导管消融结果之间的关系。
28例患者（19例男性，年龄52.3±14.2岁）接受了48次导管消融手术（范围1-6次，6次心外膜消融）。在平均18.7±15.1个月的随访期间，13例患者（46.5%）出现VT复发。年龄>50岁和∑QRSmvV1-V3/∑QRSmvV1-V6≤0.48与随访期间VT复发相关，而右室大小和急性消融结果与VT复发无关。
年龄>50岁和∑QRSmvV1-V3/∑QRSmvV1-V6≤0.48可预测ARVC和电风暴患者成功进行VT射频导管消融后VT的复发。
