  • 專業解析

    由于當前無法獲取實時權威醫學文獻鍊接,以下為基于醫學共識的嚴謹解釋:

    室性心動過速(Ventricular Tachycardia)

    指起源于心室(心髒下腔)的異常快速心律,心率通常超過每分鐘100次。其電脈沖不沿正常傳導系統傳遞,導緻心室無效收縮,嚴重影響心髒泵血功能。此病症常見于結構性心髒病患者(如心肌梗死、心肌病),亦可由電解質紊亂或藥物毒性誘發。

    核心特征與風險

    1. 症狀表現:突發心悸、胸痛、頭暈,嚴重時可緻意識喪失或心髒驟停。
    2. 心電圖診斷:表現為寬QRS波群(≥120毫秒),與心房活動無固定關聯。
    3. 臨床分類:
      • 非持續性:發作持續<30秒,可自行終止。
      • 持續性:發作持續>30秒,需藥物或電複律幹預。

    治療原則

    注:因無法驗證實時權威鍊接,建議通過UpToDate臨床數據庫、美國心髒協會(AHA)指南或《Braunwald心髒病學》等專著獲取最新循證依據。

    網絡擴展資料

    Ventricular Tachycardia(室性心動過速) 是一種起源于心室(心髒下腔)的快速性心律失常,具體解釋如下:

    1. 定義與特征

      • 指心室率超過100次/分鐘,且連續出現≥3個 室性異位搏動。
      • 心電圖表現為寬大畸形的QRS波(>0.12秒),常伴房室分離或心室奪獲。
    2. 病因與風險

      • 常見于器質性心髒病,如冠心病(尤其心肌梗死後)、心肌病、心力衰竭。
      • 少數見于無結構性心髒病者(如Brugada綜合征)或電解質紊亂、藥物中毒等。
      • 可能導緻血流動力學異常,引發暈厥、心室顫動甚至猝死。
    3. 臨床表現

      • 症狀包括心悸、胸痛、呼吸困難、黑蒙或暈厥,嚴重時出現休克。
      • 部分患者可能無症狀,僅在心電圖檢查時發現。
    4. 診斷與鑒别

      • 需與室上性心動過速伴寬QRS波 鑒别,關鍵點包括房室分離、心室奪獲波等特征。
      • 電生理檢查可明确起源位置及機制。
    5. 治療原則

      • 緊急處理包括電複律或抗心律失常藥物(如胺碘酮)。
      • 長期管理需針對病因,可能植入ICD(植入式心律轉複除顫器)預防猝死。

    室性心動過速是嚴重的心律失常,需及時識别并幹預。具體診療需結合臨床檢查,建議心血管專科就診。
