奎尼丁是应用悠久、疗效较可靠的广谱抗心律失常药物。虽然近年来电复律应用较普遍,但往往也需奎尼丁维持疗效。奎尼丁有一定的副作用,引起“晕厥”为其严重的并发病,我们过去应用奎尼丁亦发生过“晕厥”或猝死,但用药较杂,尚难完全肯定为该药所致,但最近我们遇一例在电复律后发生奎尼丁晕厥,报导于后,并提出予防意见,以供参考。 Quinidine is a long-term, more reliable efficacy of broad-spectrum anti-arrhythmic drugs. Although the application of cardioversion in recent years more common, but often also need to maintain the efficacy of quinidine. Quinidine has some side effects, causing “syncope” for its serious and concurrent disease, we used to use quinidine also had a “syncope” or sudden death, but more mixed drugs, it is difficult to fully confirm the drug caused, but We recently encountered a case of electrocardiogram occurred after Quinidine syncope, reported later, and put forward to prevent opinions for reference.
