醋丁洛尔的特点在于:相对的心脏选择性,部分激动剂作用和膜稳定性。确定其疗效还须排除室性早搏(PVC)频率自发性波动造成的假象,故本文综合三组多中心双盲交叉试验的结果,各组分别以安慰剂、心得安和奎尼丁为对照。方法:试验对象为器质性心脏病和/或室性心律失常的病人,心功能尚好(NYHAI～Ⅱ级),年龄21～70岁。试验前记录24小时动态心电图2～3次作基准,如每次记录的
Acebutolol is characterized by its relative cardiac selectivity, partial agonist action and membrane stability. To determine the efficacy of ventricular premature ventricular contraction (PVC) also need to rule out the possibility of spontaneous fluctuations in the illusion, so the article integrated three groups of double-blind multi-center cross-test results, each group were placebo, propranolol and quinidine as a control. METHODS: Patients with organic heart disease and / or ventricular arrhythmias had good cardiac function (NYHAI ~ grade Ⅱ) and were 21 to 70 years old. Record 24 hours before the test Holter 2 to 3 times as a benchmark, such as each record
