动态心电图仪消磁防护套保护皮肤及防磁性能效果

Skin protection and antimagnetic properties of magnetic protective sleeve of Holter monitor

目的探讨动态心电图仪消磁防护套对皮肤保护的作用及防磁性能。方法抽取240例接受动态心电图检查的患者，随机分成对照组和观察组，两组各120例，对照组采用常规方法佩戴心电图仪并进行常规宣教，观察组在常规宣教的同时应用自制双层消磁防护套佩戴心电图仪。在检查24h后，观察两组局部皮肤异常情况、伪差发生率，了解患者主观感受。结果观察组伪差发生6例（5．0％）、皮肤异常发生12例（10．0％），对照组伪差发生20例（16．67％）、皮肤异常发生29例（24．31％），组间比较差异具有统计学意义（P〈0．05）；观察组舒适度、安全性、牢固性、约束性评分明显优于对照组，组间比较差异具有统计学意义（P〈0．05）。结论消磁防护套的应用，可以减少动态心电图监护仪伪差发生率，更好地保护了局部皮肤，使佩戴动态心电图监护仪患者产生较好的主观体验。

Objective To explore the property of skin protection and antimagnetic property of magnetic protective sleeve of Holter monitor. Methods A total of 240 patients examined with Holter monitor were randomly divided into control group （120 cases） and observation group （120 cases）. Patients in control group wore Holter monitor with conventional methods along with routine health education. Unlike conventional methods, patients in observation group wore Hoher monitor with self-designed double-deck magnetic protective sleeve along with routine health education. We observed the exceptional situation of local skin and the incidence of pseudo difference 24 hours after examination as well as understood the subjective feelings of patients. Results There were 6 cases with pseudo difference （ 5.0% ） and 12 cases with abnormal skin （ 10.0% ） in observation group. At the same time, there were 20 cases with pseudo difference （16.67%） and 29 cases with abnormal skin （24.31%） in control group with statistically significant differences in them between two groups （ P 〈 0. 05 ）. Besides, the score of degree of comfort, safety, firmness, binding force in observation group were better than those in control group with statistically significant differences （ P 〈 0.05 ）. Conclusions The application of magnetic protective sleeve can decrease the incidence of pseudo difference of Hoher monitor, protect skin well and make patients wore Hoher monitor bold a good subjective experience.
