本文对41例多源性房性心动过速(MAT)进行临床分析。其心电图诊断标准为:散在性出现的形态不同的P波,心房率>100次/分,常伴有1:1心室传导,PP间期不规则。本组年龄45～87岁,平均74岁。在MAT发作时主要原发病为:急性呼吸道疾病28例(其中伴有慢性阻塞性肺部疾患19例,不伴有此病的9例);急性左心衰竭7例;非呼吸道疾病6例。在MAT发作时未用洋地黄者22例,其中9例以后因治疗其原发病而给予洋地黄全效量;19例在MAT发作时继续给予洋地黄维持量,其中16例病情好转出院。济地黄不能减慢患者的心房率和心室率。用盐酸奎尼丁治疗3例,苯妥英钠治疗1例,普鲁卡因酰胺和利多卡因治疗1例和电击复律治疗1例均无效。7例给予盐酸心得安口服,其剂量为5～10毫克每4～6小时一次,并调整其剂量使心室率维持在
In this paper, 41 cases of multi-source atrial tachycardia (MAT) clinical analysis. The diagnostic criteria for ECG: scattered in the form of different P wave, atrial rate> 100 beats / min, often accompanied by 1: 1 ventricular conduction, PP interval irregular. The age group of 45 to 87 years, mean 74 years old. The main primary disease in the onset of MAT was: 28 cases of acute respiratory diseases (including 19 cases of chronic obstructive pulmonary disease, 9 cases are not associated with the disease); acute left heart failure in 7 cases; non-respiratory disease in 6 cases . In the onset of MAT, 22 cases were not treated with digitalis, of which 9 cases were given the full dose of digitalis for the treatment of their primary disease. Nineteen cases were given digitalis maintenance dose at the onset of MAT, and 16 cases were cured. Rehmannia can not slow down the patient’s atrial and ventricular rate. 3 cases treated with quinidine hydrochloride, 1 case treated with phenytoin sodium, 1 case treated with procainamide and lidocaine, and 1 case treated with electric shock cardioversion. 7 cases given propranolol hydrochloride, the dose of 5 to 10 mg every 4 to 6 hours once, and adjust the dose to maintain ventricular rate at
