【摘要】 目的 觀察原發性高血壓左心室肥厚患者的心律失常情況。 方法 對2000年1月-2009年10月收治的251例原發性高血壓患者進行超聲心動圖及Holter檢查，比較有左心室肥厚（left ventricular hypertrophy，LVH）及無LVH兩組各類心律失常的發生情況。 結果 LVH組各種心律失常的發生率與非LVH組比較，差異有統計學意義（Plt;0.01）。LVH組室性心律失常及復雜性室性心律失常的檢出率為83.33%和51.85%，明顯高于非LVH組（28.67%和9.09%），差異有統計學意義（Plt;0.01）。 結論 高血壓并發LVH與心律失常的發生有一定密切關系。【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.
