异丙肾上腺素激发试验在电生理检查和射频消融术的应用及护理

Application and nursing of the isoprenaline testing in the EPS and RFCA

目的阐述在电生理检查和射频消融术中应用异丙肾上腺素激发试验来发现和确诊快速性心律失常及增加判断手术成功的合理性,论述了试验过程中如何进行全面的、科学的护理。方法对在进行射频消融术中应用异丙肾上腺素激发试验的149例患者的护理措施进行分析。结果149例行电生理检查的患者中有134例成功诱发心律失常;134例行RFCA治疗的患者手术时行Iso激发试验不能诱发心动过速为RFCA手术成功。全部受试者均顺利地完成激发试验。结论Iso激发试验在电生理检查中确诊快速心律失常类型和判断射频消融术成功中占有重要地位;良好的术前心理准备,试验中严谨的护理,充分的急救预见,是患者Iso激发试验顺利的重要保障。

Objective To evaluate the rationality of Isoprenaline（Iso） testing to discover and diagnose tachyarrhythmia in electrophysiological study（EPS） and radiofrequency catheter ablation（RFCA） and to introduce the multiplex and reasonable nursing methods during peri-testing. Methods 149 patients receiving the Iso testing in EPS for doubtful arrhythmia and/or RFCA were analyzed in nursing care.Results 134 of 149 patients were inducible tachycardia in EPS and all 134 patients were successfully finished the RFCA. The Iso testing went smoothly in every patient. Conclusions The Iso testing plays important role in diagnosis of tachyarrhythmia in EPS and effective evaluation the success of RFCA. The key points for the Iso testing are well pre-operative psychological preparation, rigorous care during testing and sufficient prediction for the related emergency treatments.
