Abstract

Atrioventricular block (AVB) is among the leading diagnoses requiring pacemaker implantation. The incidence of this cardiac conduction disorder increases with age: from the UK Biobank, a community-dwelling cohort of approximately half a million participants, conduction disorders were far more present in those ≥65 years of age versus under the age of 55 (55/10.000 vs 11/10.000, respectively). 1 AVB is defined as delayed or interrupted impulse conduction and can be caused by anatomical or func-tional disorders of the conduction system. An extrinsic or physiological AVB can be secondary to increased parasympathetic tone, and is often self- limiting and does not require therapy. Intrinsic or pathological AVB is subdivided into suprahisian and infrahisian, the being predominantly benign and the requiring is referred The main is the conduction elder
需要确定年轻房室传导阻滞患者的遗传因素和可改变因素
房室传导阻滞(AVB)是需要植入起搏器的主要诊断之一。这种心脏传导障碍的发病率随着年龄的增长而增加:来自英国生物银行,一个大约50万参与者的社区居住队列,传导障碍在≥65岁的人群中比55岁以下的人群更常见(分别为55/ 10,000和11/ 10,000)。AVB被定义为脉冲传导延迟或中断,可由传导系统的解剖或功能障碍引起。外源性或生理性AVB可继发于副交感神经张力增加,通常是自限性的,不需要治疗。内源性或病理性AVB又分为上肌和下肌,以良性为主,以传导性为主
