二年来,我们在30例预激综合征(下称WPW)中发现伴发心房颤动者3例(B型2例,A型一例),均有反复发作、心室率快、QRS波增宽畸形以及夹有正常或接近正常波形等特点。有2例静脉注射西地兰无效,其中一例的室率反而加速;但在静脉注射利多卡因后,3例的房颤均消失。可见,这种房颤在表现和治疗上均有特征性。病例报告 [例1] 女,46岁。几年来经常发作心动过速,这次发作来院急诊,心脏听诊无明显杂音,心率约150次/分,律不齐,血压140/90毫米汞柱。胸透心脏不大,心电图示宽而畸形的QRS波群,误诊为室性心动过速,静脉注射利多
In the past two years, we found that in 30 cases of WPW (WPW), 3 cases were accompanied by atrial fibrillation (2 cases of type B and 1 case of type A). All of them had recurrent, fast ventricular rate and widening of QRS wave And the folder with normal or near normal waveform and so on. In 2 cases, cedilanid was not effective, and in one case, the ventricular rate was accelerated. However, all three cases of atrial fibrillation disappeared after intravenous injection of lidocaine. Can be seen that this kind of atrial fibrillation in the performance and treatment are characteristic. Case Report [Example 1] Female, 46 years old. Frequent seizures in recent years, tachycardia, the attack to the hospital emergency room, auscultation heart no obvious noise, heart rate of about 150 beats / min, irregular blood pressure, blood pressure 140/90 mm Hg. Chest through the heart is not large, ECG shows wide and abnormal QRS complex, misdiagnosed as ventricular tachycardia, intravenous injection of more
