高血压是最常见的心血管疾病。长期血压升高可导致左心室肥厚（ＬＶＨ），ＬＶＨ又可引起心肌缺血，影响左室收缩和舒张功能，诱发室性心律失常。为观察高血压患者ＬＶＨ对心脏功能的影响，作者对６９例高血压患者进行彩超多普勒（Ｄｏｐｐｌｅｒ）和２４ｈ动态心电图（ＤＣＧ
Hypertension is the most common cardiovascular disease. Long-term high blood pressure can lead to left ventricular hypertrophy (LVH), LVH can cause myocardial ischemia, affecting left ventricular systolic and diastolic function, induced ventricular arrhythmias. In order to observe the effect of LVH on cardiac function in patients with hypertension, 69 hypertensive patients underwent Doppler and 24h electrocardiogram (DCG)
