【摘要】 目的 观察原发性高血压左心室肥厚患者的心律失常情况。 方法 对2000年1月-2009年10月收治的251例原发性高血压患者进行超声心动图及Holter检查，比较有左心室肥厚（left ventricular hypertrophy，LVH）及无LVH两组各类心律失常的发生情况。 结果 LVH组各种心律失常的发生率与非LVH组比较，差异有统计学意义（Plt;0.01）。LVH组室性心律失常及复杂性室性心律失常的检出率为83.33%和51.85%，明显高于非LVH组（28.67%和9.09%），差异有统计学意义（Plt;0.01）。 结论 高血压并发LVH与心律失常的发生有一定密切关系。【Abstract】 Objective To analyze the condition of arrhythmia in the patients with primary hypertension combined with left ventricular hypertrophy. Methods A total of 251 patients with primary hypertension from January 2000 to October 2009 were selected. All the patients had undergone the examinations of ultrasonic cardiogram, 12-lead electrocardiogram and Holter test to compare the incidence of arrhythmia between LVH and non-LVH group. Results There were significant differences in the incidences of arrhythmia between the two groups (Plt;0.01). Furthermore, the incidence of ventricular arrhythmias and complexity of ventricular arrhythmias of the patients in LVH group was 83.33% and 51.85% respectively, significantly higher than that in non-LVH group (28.67% and 9.09%; Plt;0.01). Conclusion Primary hypertension combined with LVH is relevant to arrhythmias.
