Abstract

Background

Data on the predictors of percutaneous stellate ganglion block (PSGB) efficacy in electrical storm are scanty.

Objective

We aimed to assess whether PSGB efficacy is influenced by the arrhythmia type and cycle length before the procedure.

Methods

This is a subanalysis of the multicenter STAR study. The population was stratified into 3 groups according to the median cycle length of the latest ventricular arrhythmia before PSGB: ventricular fibrillation (VF), fast ventricular tachycardia (VT), and slow VT. The primary outcome was the number of treated arrhythmic episodes (with antitachycardia pacing or direct current shocks) in the hour immediately after PSGB compared with the hour before.

Results

We considered 139 PSGBs from 112 patients divided into VF (51 procedures), fast VT (44 procedures, VT cycle <375 ms), and slow VT (44 procedures, VT cycle ≥375 ms). The number of treated arrhythmic episodes in the hour after every PSGB was significantly lower compared with the hour before in all groups (VF: 0 [0–1] vs 5 [2–8], P < .001; fast VT: 0 [0–0] vs 1 [0–6.5], P < .001; slow VT: 0 [0–0] vs 1 [0–4.5], P = .001). In analyzing the reduction of the number of antitachycardia pacing sequences or direct current shocks from the hour before to the hour after PSGB, a significant trend was observed across the groups (Jonckheere-Terpstra trend P < .001), and a significant difference was observed in comparing slow VT vs VF and fast VT vs VF but not in comparing slow VT vs fast VT. VF was independently associated with the probability of reduction of treated events after PSGB.

Conclusion

PSGB is an effective treatment of electrical storm in patients with all types of ventricular arrhythmias. However, its effectiveness was more pronounced in patients with VF.

根据室性心律失常周期长度确定经皮星状神经节阻滞的疗效：STAR 研究的事后子分析。

背景：有关经皮星状神经节阻滞术（PSGB）在电风暴（ES）中疗效预测因素的数据很少：目的：评估经皮星状神经节阻滞（PSGB）疗效是否受术前心律失常类型和周期长度的影响：多中心 STAR 研究的子分析。方法：这是一项多中心 STAR 研究的子分析，根据 PSGB 术前最近一次室性心律失常的中位周期长度将人群分为三组：室颤（VF）、快速-VT 和慢速-VT。主要结果是PSGB后一小时内与PSGB前一小时相比，接受治疗的心律失常发作次数（使用ATP和/或DC冲击）：我们对 112 名患者的 139 次 PSGB 进行了研究，其中 51 次为 VF，44 次为快速 VT（VT 周期）：PSGB是治疗各种类型室性心律失常患者ES的有效方法。然而，PSGB对VF患者的疗效更为显著。
