目的

探讨24 h动态心电图评估超声引导下经皮心肌内室间隔射频消融术(PIMSRA,Liwen术式)治疗梗阻性肥厚型心肌病(HOCM)致心律失常风险。

方法

选取2016年6月至2018年7月在西京医院行Liwen术式治疗HOCM患者35例,分别在Liwen术式治疗HOCM术前以及术后1年,采用24 h动态心电图获取室性心律失常、房性心律失常以及心率变异性参数,采用配对样本t检验和配对Wilcoxon符号秩和检验比较术前和术后上述参数的变化。

结果

消融前后最大心率、最低心率、平均心率,差异均无统计学意义(P均>0.05);室性早博总数、成对室性早博总、多源室性早博以及Lown′s分级,差异均无统计学意义(P均>0.05);消融前后室上性早博总数、成对室上性早博总数、室上性心动过速总数,差异均无统计学意义(P均>0.05);消融前后最大QT以及最大QTc无显著变化,差异均无统计学意义(P均>0.05);消融前后心率变异性参数,差异均无统计学意义(P>0.05)。

结论

Liwen术式治疗HOCM不增加术后短期心律失常风险,其远期风险需要大样本长期观察。

Objectives

To evaluate the risk of arrhythmia in patients with hypertrophic obstructive cardiomyopathy (HOCM) treated by echocardiography-guided percutaneous intramyocardial septal radiofrequency ablation (PIMSRA) with 24-hour Holter.

Methods

Before and 1 year after PIMSRA, the parameters of ventricular arrhythmia, atrial arrhythmia, and heart rate variability were obtained by 24-hour Holter. The difference of these parameters before and after operation were compared by paired sample t test and paired Wilcoxon signed rank sum test.

Results

There was no significant difference in heart rate, ventricular arrhythmia, or supraventricular arrhythmia before and 1 year after PIMSRA (P>0.05). Maximum QT and maximum QTc did not differ significantly between before and 1 year after PIMSRA (P>0.05). There was also no significant difference in heart rate variability before and 1 year after PIMSRA (P>0.05).

Conclusion

PIMSRA does not increase the risk of short-term arrhythmia in patients with HOCM. Further study in a large number of patients is needed for assessing long-term risk.
