Little attention has been paid to the atrial fibrillatory waves (f waves) in paroxysmal atrial fibrillation. The present study attempted (1) to compare the f wave size in paroxysmal atrial fibrillation with that in persistent fibrillation, and (2) to examine whether the f wave size can predict the development of persistent from paroxysmal atrial fibrillation. The size of the f waves was measured in 60 patients with paroxysmal atrial fibrillation of non-rheumatic etiology (group A), 87 patients with persistent atrial fibrillation of non-rheumatic etiology (group B), and 34 patients with persistent atrial fibrillation of rheumatic etiology (group C). The f wave size in group A was 1.1 +/- 0.1 mm (mean +/- SE) which was significantly smaller than 1.6 +/- 0.1 mm in group B and 2.2 +/- 0.2 mm in group C (p less than 0.01, respectively). Among patients with paroxysmal atrial fibrillation, persistent atrial fibrillation developed in 9 of 19 patients (47.4%) with f wave size of 1.2 mm or more, and only in 5 of 41 patients (12.2%) with f wave size of less than 1.2 mm. These results indicate that paroxysmal atrial fibrillation generally has smaller f waves than persistent atrial fibrillation, but that the presence of larger f waves indicates potential development of persistent atrial fibrillation.
阵发性心房颤动中的心房颤动波（f波）一直未受到太多关注。本研究试图（1）比较阵发性心房颤动与持续性心房颤动中的f波大小，以及（2）检验f波大小是否能够预测阵发性心房颤动向持续性心房颤动的发展。对60例非风湿性病因的阵发性心房颤动患者（A组）、87例非风湿性病因的持续性心房颤动患者（B组）和34例风湿性病因的持续性心房颤动患者（C组）的f波大小进行了测量。A组的f波大小为1.1±0.1mm（均值±标准误），显著小于B组的1.6±0.1mm和C组的2.2±0.2mm（p值均小于0.01）。在阵发性心房颤动患者中，f波大小为1.2mm或更大的19例患者中有9例（47.4%）发展为持续性心房颤动，而f波大小小于1.2mm的41例患者中仅有5例（12.2%）发展为持续性心房颤动。这些结果表明，阵发性心房颤动的f波通常比持续性心房颤动的小，但较大f波的存在表明有发展为持续性心房颤动的可能性。
