冠心病心肌缺血严重者左室舒张末期压增高,左房舒张末压也跟着增高,在体表心电图上表现 V_1导联 P 波终末电势(PTFV_1)负值增大。本文对24小时动态心电图(Holter)检出有缺血性 ST 段下移的185例连续患者的缺血总负荷、与安静时患者体表心电图PTFV_1及 Holter 监测中短阵房速发生率的关系进行了研究,探讨它们之间的关系。1 材料与方法1.1 研究对象:病人来源于1991年8月～1995年7月作 Holter 检查经计算机检出心肌缺血总段数与缺血
Severe myocardial ischemia in patients with left ventricular end-diastolic pressure increased, left atrial end-diastolic pressure also followed an increase in the surface ECG showed V_1 lead P wave terminal potential (PTFV_1) increased negative. In this paper, the total ischemic load of 185 consecutive patients with ischemic ST-segment elevation in 24-hour Holter was compared with the PTFV_1 of body surface electrocardiogram and the incidence of short-term atrial-rate in Holter monitoring at rest Conducted a study to explore the relationship between them. 1 Materials and Methods 1.1 Study: Patients from August 1991 to July 1995 Holter examination by computer detection of the total number of ischemic segments and ischemia
