预激综合征(WPW)病人并发快速(心)房颤(动)时存在猝死的危险。但一般 WPW病人猝死是极少的,约0～4%,主要见于器质性心脏病,或是由一些药物所致者。本文以电生理测试房颤时其最短 R-R 间期≤250ms或旁路前向传导有效不应期≤250ms 作为危险标准,测定非侵入性运动试验和普鲁卡因胺,心律平药物试验来确定 WPW 病人猝死危险性的敏感性,特异性和预示值。
There is a risk of sudden death in patients with WPW (rapid atrial fibrillation). However, the general WPW patients with sudden death is minimal, about 0 ~ 4%, mainly seen in organic heart disease, or caused by some drugs. In this paper, the electrophysiological test of atrial fibrillation, the shortest RR interval ≤ 250ms or the effective conduction of refractory pre-shunt ≤ 250ms as a risk criterion for the determination of non-invasive exercise test and procaine amine, arrhythmia drug test to determine Sensitivity, specificity and predictive value of the risk of sudden death in patients with WPW.
