虽然风心病和冠心病心房纤颤(Af)时的 f 波大小已有定论,但对阵发性 Af 和持久性 Af 的 f 波差别却很少注意。我们对非风心病阵发性 Af 的 f 波大小进行了测量,同非风心病持久性 Af 进行对照,以检验阵发性Af 的 f 波振幅的临床意义。临床资料病例选择:连续观察我院1980年1月～1985年12月非风心病阵发性 Af 病例30例。男14例,女16例,年龄22～77岁,其中冠心病22例,甲亢心脏病2例、肺心病2例、心脏神经官能症2例、脑出血1例、胃炎1例。已用抗心律失常药物者被去除。如住院期间有两份以上的心电图,则只测量最早的那一份心电图。对照组选取同期住院非风心病持久性 Af 病例31 Although the magnitude of f-wave at rheumatic heart disease and coronary heart disease with atrial fibrillation (Af) has been definitive, the f-wave differences between paroxysmal Af and persistent Af are rarely observed. We measured the f-wave size of paroxysmal Af in non-rheumatic diseases and compared it with non-rheumatic persistent Af to test the clinical significance of the f-wave amplitude of paroxysmal Af. Clinical data Case selection: continuous observation of our hospital January 1980 ~ December 1985 non-rheumatic paroxysmal Af cases 30 cases. There were 14 males and 16 females, aged 22-77 years. Among them, 22 were coronary heart disease, 2 hyperthyroid heart disease, 2 pulmonary heart disease, 2 cardiac neurosis, 1 cerebral hemorrhage and 1 gastritis. Antiarrhythmic drugs have been removed. If there are more than two ECGs during hospitalization, only the earliest one is measured. Patients in the control group were enrolled in a cohort of patients with non-rheumatic persistent Af
