体位改良的Valsalva动作在终止阵发性室上性心动过速中的疗效观察

Observation on the therapeutic efficacy of position modified Valsalva maneuver in termination of paroxysmal supraventricular tachycardia

目的探讨体位改良Valsalva动作(PMVM)对终止阵发性室上性心动过速(PVST)的疗效。方法选取2019年1—12月本院收治的PVST患者72例为研究对象,依据随机数表法分为对照组与观察组,每组各36例,其中对照组采取标准Valsalva动作开展治疗,观察组采取PMVM开展治疗,比较两组的复律情况、治疗前后右侧颈内静脉前后径及左右径和不良反应出现情况。结果观察组的复律失败率为44.44%,低于对照组的75.00%;同时一次复律成功率为41.67%,高于对照组的11.11%(P<0.05)。治疗后,观察组右侧颈内静脉的左右径与前后径比长于对照组(P<0.05)。两组头晕、肌肉骨骼痛、气促、高血压以及低血压等不良反应比较,差异无统计学意义(P>0.05)。结论予以PVST患者PMVN疗效确切,能提升其复律成功率,扩大其右侧颈内静脉内径,同时不会增加不良反应,有着较高安全性,操作方便,值得采用。

Objective To explore the therapeutic efficacy of position modified Valsalva maneuver(PMVM)in termination of paroxysmal supraventricular tachycardia(PVST).Methods A total of 72 patients with PVST admitted to our hospital from January 2019 to December 2019 were selected,and they were divided into the control group(n=36)and the observation group(n=36)according to the random number table method.The control group was treated with standard Valsalva maneuver,while the observation group was treated with PMVM.The cardioversion,anteroposterior diameter,left-right diameter of right internal jugular vein and adverse reactions(ADRs)of the two groups were counted and compared.Results The failure rate of cardioversion in the observation group was 44.44%,lower than 75.00%in the control group,and the success rate of one-time cardioversion in the observation group was 41.67%,higher than 11.11%in the control group(P<0.05).After treatment,the left-right diameter and the front-back diameter of the right internal jugular vein in the observation group were longer than those in the control group(P<0.05).There were no significant differences in ADRs such as dizziness,musculoskeletal pain,shortness of breath,hypertension and hypotension between the two groups(P>0.05).Conclusion PMVN is effective on patients with PVST,which can improve the success rate of cardioversion,enlarge the inner diameter of the right internal jugular vein,and at the same time,it will not increase the occurrence of ADRs.It has high safety and convenient operation and is worthy of application.
