本文应用口服心得安法对β—受体高敏者与冠心病患者两组共69例心电图 ST—T改变的影响进行观察,所得结果是β受体高敏组44例中阳性40例(91%),冠心病组25例中阳性仅1例(4%)其阳性率明显低于前者。对β受体高敏组阴性者4例经加大剂量给予心得安40毫克口服,于1小时后复查心电图 ST—T 均恢复正常。因此作者认为口服心得安法,对β—受体高敏与器质性心脏病可以提供鉴别诊断的根据,在临床上有重要参考意义。作者指出心得安试验结果阴性者似可除外β—受体高敏,如同时亦能除外其它影响心电图 ST—T 改变的因素应考虑有器质性心脏病的可能。作者推荐使用口服心得安法,认为此方法方便、可靠,便于临床使用和观察,并使受检者易于接受,尚可在短时间内加大剂量,重复试验。
In this paper, the application of oral Andean on β-receptor hypersensitivity and coronary heart disease in patients with a total of 69 cases of ECG ST-T changes were observed in the results of β receptor hypersensitivity group 44 cases were positive in 40 cases (91%), , The positive rate of coronary heart disease group of 25 cases was only 1 case (4%) was significantly lower than the former. On the high-sensitivity β-receptor group, 4 cases by increasing the dose of propranolol 40 mg orally, after 1 hour ECG ST-T were back to normal. Therefore, the author believes that oral Andean, β-receptor hypersensitivity and organic heart disease can provide a basis for the differential diagnosis, has important clinical significance. The authors point out that propranolol may be negative in test results except for β-receptor hypersensitivity, which can also be excluded at the same time. Other factors that may affect ST-T changes of electrocardiogram should be considered organic heart disease. The authors recommend the use of oral experience Anfa, that this method is convenient, reliable, easy to clinical use and observation, and make the subject easy to accept, but also in a short period of time to increase the dose and repeat the test.
