房室传导阻滞（Atrioventricular Block）是心脏电传导系统异常的一种病理状态，指心脏电信号从心房到心室的传导过程受阻，导致心跳节律异常或心动过缓。根据阻滞程度，可分为三型：
一度房室传导阻滞
电信号通过房室结时速度减慢，但所有信号仍能传递至心室。心电图表现为PR间期延长（>0.20秒），通常无症状，可能由药物（如β受体阻滞剂）或心肌炎引起。
二度房室传导阻滞
三度房室传导阻滞（完全性）
心房与心室电活动完全分离，心室依赖逸搏心律维持，心率常低于40次/分，患者可能出现晕厥或心力衰竭，需紧急植入心脏起搏器。
病因包括冠心病、心肌病、心脏手术损伤、先天畸形及药物（如地高辛）。诊断依赖心电图和动态心电监测，治疗需根据阻滞程度选择观察、药物调整或起搏器植入。权威医学指南（如《美国心脏病学会临床决策路径》）建议三度阻滞患者立即接受起搏治疗以降低猝死风险。
Atrioventricular Block（房室传导阻滞） 是心脏电信号传导异常的医学术语，指从心房到心室的电冲动传导延迟或中断。以下为详细解释：
房室传导阻滞（AVB）是心脏电信号通过房室结时发生延迟、部分或完全中断的现象。正常房室传导时间为0.12-0.20秒，若超过0.20秒则为一度阻滞；若部分信号中断为二度阻滞；完全中断则为三度阻滞。
轻度阻滞可能无症状，重度（如三度阻滞）可导致晕厥、心源性猝死，需起搏器治疗。
如需进一步了解分型心电图特征或治疗方案，可参考医学专业文献或权威教材。
