动脉血压长期持续增高可引起左心室肥厚、劳损、扩张等一系列器质性病变,最后导致充血性心力衰竭。为了及时了解其左心负荷过重情况及其左心功能损害程度,常须应用心电图及超声心动图等无创性器械检查,特别是超声心动图检查对确定心室壁的厚度,判断左心室的功能状况颇有价值。本文的研究目的在于对高血压病所致的左心病变,先以心电图诊断指标作基础,分析其与超声心动图有关在室病变及其功能影响
Long-term continuous increase in arterial blood pressure can cause left ventricular hypertrophy, strain, expansion and a series of organic diseases, and finally lead to congestive heart failure. In order to understand the situation of left heart overload and left ventricular dysfunction, often need to apply noninvasive ECG and echocardiography equipment, especially echocardiography to determine the thickness of the ventricular wall to determine the function of the left ventricle The situation is quite valuable. The purpose of this paper is to study the left ventricular pathological changes caused by hypertension, based on the diagnostic criteria of electrocardiogram (ECG)
