大剂量维生素C抢救急型克山病的完全性房室传导阻滞——附40例临床分析

1.本文报导了应用大量VC(10克)静脉注射抢救急型克山病CAVB 40例的结果,得救率为82.5%,通过CAVB发生前后一系列心电图监测,时CAVB的发生、发展和转归作了分析与讨论。2.对影响疗效和预后的因素进行了分析。建议按心功能状态、收缩血压、心室率、QRS波群间期、ST-T改变等5项作为观察指标,用累积记分法,以估计预后,凡记分在15分以上者预后不良。

Large Doses of Vitamin C Gives an Emergency Treatment to Complete A-V Block of Acute Serious Type of Keshen Disease (clinical analysis of 40 cases)

Intravenous injection of large doses of Vitamin C (10g) gives an emergency treatment to 40 cases of complete A-V block of acute serious typeof keshan disease. The rate of recovery reaches 82. 5%. By monitoring a seriesof the electrocardiograms before and after complete A-V block, it has befound that most complete A-V block (about 80%)is deveploped by right bun-dle branch block. After treatment with large doses of Vitamin C, completeA-V block disappears rapidly, without a case turning into a permanent co-mplete A-V block. In view of the analysis of the factors affecting the cur-ative effect and prognosis of complete A-V block, we recommend that he-art function state, systole blood pressure, venticle rates, QRS complex waveintervals and ST-T segment change be usedas a standard observation and themethod of accumulating score in order to estimate prognosis. If the score isabout 15, there will be a poor prognosis.
