目的探讨高血压早期左房受损的发生过程与表现。方法通过超声心动图和动态心电图等检查对151例高血压患者进行观察、研究。结果左房扩大发生于左室重构以先,且贯穿于高血压左室重构的始终,房性心律失常发生率高于正常对照组,具有显著的统计学意义。结论高血压左房扩大是高血压心脏受损的更早期表现,是引起复杂房性心律失常尤其是心房颤动的重要因素,不容忽视。 Objective To investigate the incidence and manifestation of left atrial appendage in the early stage of hypertension. Methods 151 cases of hypertension were observed and studied by echocardiography and Holter monitoring. Results Left atrial enlargement occurred first in left ventricular remodeling, and throughout the left ventricular remodeling of hypertension, the incidence of atrial arrhythmia than the normal control group, with significant statistical significance. Conclusions Hypertensive left atrial enlargement is an earlier manifestation of heart damage in hypertension and is an important factor that causes complex atrial arrhythmias, especially atrial fibrillation, which can not be ignored.
