摘要
背景：P 波峰值时间（PWPT）是阵发性心房颤动（PAF）的预测指标。高功率短时消融与改善环行肺静脉电隔离（PVI）的耐久性有关。我们研究了高功率短时程 PVI 对 PAF 患者 PWPT 的影响：在 111 名 PAF 患者中，91 人接受了射频消融治疗（消融组），20 人接受了药物治疗（对照组）。同时使用 VIZIGO 鞘和 STSF 导管（Biosense Webster，加利福尼亚州，美国）进行高功率短时周向 PVI，前壁和后壁的消融指数值分别为 500 和 400。对患者进行了 12 个月的随访：结果：消融组患者术前的脉搏波速度与对照组相似：PWPT II = 54.38 ± 6.18 ms vs. 54.35 ± 6.12 ms（P > 0.05），PWPT V1 = 54.19 ± 6.21 ms vs. 54.31 ± 6.08 ms（P > 0.05）。消融组所有患者在手术中均实现了环周 PVI。在 12 个月的随访中，有 7 例房颤复发。消融组患者术后 12 个月的 PWPT 短于术前值：PWPT II = 49.39 ± 7.11 ms vs. 54.38 ± 6.18 ms (p 1 = 47.69 ± 7.01 ms vs. 54.19 ± 6.21 ms (p 1 = 50.84 ± 7.05 ms vs. 47.19 ± 6.27 ms, (p 0.05)，PWPT V1 = 53.89 ± 6.01 ms vs. 54.31 ± 6.08 ms (p > 0.05)：结果表明，高功率短时 PVI 对 PWPT 有积极影响，而 PWPT 是 PAF 的预测指标。
The effect of high-power short-duration pulmonary vein isolation on PWPT-a predictor of paroxysmal atrial fibrillation.
Background: The P wave peak time (PWPT) is a predictor of paroxysmal atrial fibrillation (PAF). High-power short-duration ablation has been associated with improved durability of circumferential pulmonary vein electrical isolation (PVI). We investigated the effect of high-power short-duration PVI on PWPT in patients with PAF.
Methods: Out of 111 patients with PAF, 91 received radiofrequency ablation (ablation group) and 20 received medication treatment (control group). A VIZIGO sheath and an STSF catheter (Biosense Webster, CA, USA) were used together for high-power short-duration circumferential PVI at ablation index values of 500 and 400 for the anterior and posterior walls, respectively. The patients were followed up for 12 months.
Results: The preoperative PWPT in the ablation group was similar to that in the control group: PWPT II = 54.38 ± 6.18 ms vs. 54.35 ± 6.12 ms (p > 0.05), PWPT V1 = 54.19 ± 6.21 ms vs. 54.31 ± 6.08 ms (p > 0.05), respectively. Circumferential PVI was achieved for all patients in the ablation group during the operation. At the 12-month follow-up, there were seven cases of AF recurrence. The PWPT in the ablation group 12 months postoperatively was shorter than the preoperative value: PWPT II = 49.39 ± 7.11 ms vs. 54.38 ± 6.18 ms (p < 0.001), PWPT V1 = 47.69 ± 7.01 ms vs. 54.19 ± 6.21 ms (p < 0.001). The PWPT in the patients with AF recurrence was significantly longer than that in the non-recurrence patients: PWPT II = 50.48 ± 7.12 ms vs. 47.33 ± 6.21 ms (p < 0.001), PWPT V1 = 50.84 ± 7.05 ms vs. 47.19 ± 6.27 ms, (p < 0.001). The PWPT of the control group at the 12-month follow-up was similar to the baseline level: PWPT II = 54.32 ± 6.20 ms vs. 54.35 ± 6.12 ms (p > 0.05), PWPT V1 = 53.89 ± 6.01 ms vs. 54.31 ± 6.08 ms (p > 0.05).
Conclusion: The results showed that high-power short-duration PVI had a positive effect on PWPT, which is a predictor of PAF.
