房室傳導阻滞(Atrioventricular Block)是心髒電傳導系統異常的一種病理狀态,指心髒電信號從心房到心室的傳導過程受阻,導緻心跳節律異常或心動過緩。根據阻滞程度,可分為三型:
一度房室傳導阻滞
電信號通過房室結時速度減慢,但所有信號仍能傳遞至心室。心電圖表現為PR間期延長(>0.20秒),通常無症狀,可能由藥物(如β受體阻滞劑)或心肌炎引起。
二度房室傳導阻滞
三度房室傳導阻滞(完全性)
心房與心室電活動完全分離,心室依賴逸搏心律維持,心率常低于40次/分,患者可能出現暈厥或心力衰竭,需緊急植入心髒起搏器。
病因包括冠心病、心肌病、心髒手術損傷、先天畸形及藥物(如地高辛)。診斷依賴心電圖和動态心電監測,治療需根據阻滞程度選擇觀察、藥物調整或起搏器植入。權威醫學指南(如《美國心髒病學會臨床決策路徑》)建議三度阻滞患者立即接受起搏治療以降低猝死風險。
Atrioventricular Block(房室傳導阻滞) 是心髒電信號傳導異常的醫學術語,指從心房到心室的電沖動傳導延遲或中斷。以下為詳細解釋:
房室傳導阻滞(AVB)是心髒電信號通過房室結時發生延遲、部分或完全中斷的現象。正常房室傳導時間為0.12-0.20秒,若超過0.20秒則為一度阻滞;若部分信號中斷為二度阻滞;完全中斷則為三度阻滞。
輕度阻滞可能無症狀,重度(如三度阻滞)可導緻暈厥、心源性猝死,需起搏器治療。
如需進一步了解分型心電圖特征或治療方案,可參考醫學專業文獻或權威教材。
