传统的右心室心尖部(RVA)起搏,以其电极容易固定和良好的稳定性、安全性,被公认为是传统而经典的起搏部位。近年来,随着生理性起搏研究的深入,RVA起搏弊端显示出来,RVA改变了心脏正常的激动传导顺序,造成左右心室收缩失同步,长期的RVA对心脏结构及功能均产生不良影响。本研究通过比较超声心动图、脑钠肽(BNP)等,分析右心室流出道(ROVT)间隔部起搏与RVA对左心功能的影响,总结2种不同部位起搏的优劣报告如下。
The traditional right ventricular apex (RVA) pacing, with its electrodes easily fixed and good stability, safety, is recognized as a traditional and classic pacing site. In recent years, along with the study of physiological pacing, the disadvantages of RVA pacing appear. RVA changes the normal activation and conduction sequence of the heart, resulting in systolic left and right ventricular systole. Long-term RVA has adverse effects on cardiac structure and function. In this study, by comparing echocardiography, brain natriuretic peptide (BNP), etc., right ventricular outflow tract (ROVT) septal pacing and RVA on left ventricular function, summarize the advantages and disadvantages of 2 different parts of pacing are reported below.
