摘要


一個心悸的55歲女性其心電圖顯示心房顫動,在接受心臟電氣生理學檢查時發現可誘發的房室結迴旋頻脈。電燒掉慢速傳導路徑之後,房室結迴旋頻脈和心房顫動便無法再被誘發。在兩年的追蹤當中,以病人症狀及霍特氏心電圖來評估,並無心房顫動再發的證據。因此我們推論此病人之心房顫動是由房室結迴旋頻脈所引起。在成功的將房室結迴旋頻脈電燒術後,即不需再對於心房顫動作電燒術。

並列摘要


Inducible atrioventricular nodal reentrant tachycardia was demonstrated by electrophysiological studies in a 55-year-old female who suffered from intermittent palpitation, in which paroxysmal atrial fibrillation (AF) was consistently documented by electrocardiogram recordings. After ablation of the slow pathway, the atrioventricular nodal reentrant tachycardia and AF were not inducible. During 2 years of follow-up, there were no recurrences of AF in terms of symptoms or findings from Holter electrocardiograms. We suggest that the AF was triggered by the atrioventricular nodal reentrant tachycardia and the successful ablation of atrioventricular nodal reentrant tachycardia was associated with freedom arising from ablation of AF.
