作者随访了30例左前分支阻滞(LAH)的患者,随访时间为半年至11年,平均4年半。经随访发现28例患者临床表现与初检时类同,2例根据心电图运动试验阳性而诊断为冠心病。年龄在40岁以上及电轴左偏超过-45°,同时伴有高血压、高血脂者,其收缩时间间期(STI)、心尖搏动图(ACG)、超声心动图(UCG)以及胸部X线检查等项目的异常发生率较高。因此,(1)LAH本身予后较为良好;(2)对STI、ACG、UCG以及X线异常者应引起注意:(3)在评定LAH病程演变时,心向量图似优于心电图。
The authors followed up 30 patients with left anterior branch block (LAH) who were followed up for a period of six to 11 years, an average of 4 and a half years. Follow-up found 28 patients with clinical manifestations and the same type of initial examination, 2 cases were diagnosed as coronary heart disease based on positive ECG test. Age over 40 years old and left axis over -45 °, accompanied by hypertension, hyperlipidemia, systolic time period (STI), apical beat chart (ACG), echocardiography (UCG) and chest X Line inspection and other projects a higher incidence of abnormalities. Therefore, (1) LAH itself is better after admission; (2) attention should be given to STI, ACG, UCG, and X-ray abnormalities; (3) Cardiogram better than electrocardiogram in assessing the evolution of LAH course.
