心脏再同步化(CRT)已成为目前起搏器治疗研究的热点,心室的再同步化使心力衰竭病人心脏的收缩和舒张功能改善,心房的再同步化使房性心律失常的控制成为可能,心房功能得到改善,心室和心房的再同步化均能使患者在长期的起搏器治疗中获益.结合国内外文献对起搏位点优化促进心脏再同步化,改善心功能问题的研究近况、部分机制、方法及适应症作一综述. Cardiac resynchronization (CRT) has become a hotspot in the research of pacemaker treatment. The resynchronization of the ventricle can improve the systolic and diastolic function of heart in patients with heart failure. Atrial resynchronization makes it possible to control atrial arrhythmia, Atrial function improved, resynchronization of ventricle and atrium can make patients benefit from long-term pacemaker treatment.Considering domestic and foreign literature on the optimization of pacing site to promote cardiac resynchronization and improve cardiac function , Some mechanisms, methods and indications for a review.
