本文报告１０３例无冠心病临床表现的高血压患者ＳＴ段压低与室性心律失常及心脏昼夜节律变化的关系。结果表明，在高血压病患者Ｈｏｌｔｅｒ监测示心电图ＳＴ段压低呈缺血样改变者占３０．１％。通过有无ＳＴ段压低改变两组比较，发现有ＳＴ段压低组室性心律失常发生率比较高，并且ＳＴ段压低和室性心律失常的存在似与心脏昼夜节律变化有关。
This article reports the relationship between ST-segment depression and ventricular arrhythmia and cardiac circadian rhythm in 103 patients with hypertension without clinical manifestations of coronary heart disease. The results showed that Holter monitoring in patients with hypertension showed ST-segment depression was ischemic-like changes accounted for 30.1%. The presence of ST-segment depression and ventricular arrhythmia was associated with a change in cardiac circadian rhythm.
