因体位改变而引起不同程度的房室传导阻滞可称为体位性房室传导阻滞,表现在卧位时出现传导阻滞而在坐位或立位时恢复正常,因此亦有称卧位性房室传导阻滞。一般认为系由于迷走神经张力增高所致,对诊断心肌病变无临床价值,在临床上往往以此来鉴别功能性或是器质性房宣传导阻滞。但亦有作者认为,在心脏病变所致房室传导阻滞亦可在立位时消失,因此不能单凭此点来鉴别。本文结合体位性房室传导阻滞6例进行分析及随访,以探讨 Due to changes in body posture caused by varying degrees of atrioventricular block can be referred to as atrioventricular block, manifested in the supine position when the conduction block in the sitting or standing position back to normal, it is also known as lying Atrioventricular block. Is generally believed that due to increased vagal tone due to the diagnosis of myocardial disease has no clinical value, often in clinical practice to identify functional or organic atrial propaganda block. However, some authors believe that in the heart disease caused by atrioventricular block can also disappear in the standing position, it can not be identified by this point alone. This article combined with body position atrioventricular block in 6 cases were analyzed and followed up to explore
