1952—1964年23,764例心电图检查中属束支传导阻滞者占1.04%,占器质性心脏病的3%。右侧:左侧为2.8:1。在右侧,不完全阻滞:完全阻滞为1:1.6;而在左侧为1:2.6。在男性左右侧,完全或不全阻滞均较女性多。右侧的发病高峰在20—30岁间而在左侧为60—70岁间。右束支不全阻滞最常见的原因为风湿性心脏病(32.8%)而右束支完全阻滞则为缺血性心脏病(45.1%),左支完全阻滞的原因为缺血性心脏病更多见(74.2%)。右束支阻滞
In 1952-1964 23,764 cases of electrocardiography in the bundle branch block accounted for 1.04%, accounting for 3% of organic heart disease. Right: 2.8: 1 on the left. On the right, incomplete block: total block to 1: 1.6; and on the left to 1: 2.6. Left and right sides of men, more or less complete or incomplete block. The peak incidence of the right side of the age of 20-30 in the left for the 60-70 years old. The most common cause of right bundle branch block was rheumatic heart disease (32.8%) and right bundle branch block was ischemic heart disease (45.1%). The cause of complete block of the left branch was ischemic heart The disease was more common (74.2%). Right bundle branch block
