心室晚电位(Ventricular late potentials,VLP)与室性心动过速、心室颤动等恶性心律失常的关系已见诸多报道。而应用信号平均心电图(Signal averag electrocardiogram,SAECG)技术检测房性心律失常报道甚少。为了评价SAECG技术预测患者发生心房颤动的价值,作者对正常人、有阵发性心房颤动史者进行了SAECG的检测,初步探讨SAECG的心房波时限与心房颤动的关系。 1.对象:正常组33例,男18例,女15例,年龄15～65(平均43.7±12.8)岁,经病史、体检、心电图、X线以及心脏超声等检查证实无心脏扩大和其他明显器质性疾病与房性心律失常。阵发性心房颤动组19例,男13例,女6例,年龄28～69(平均49.7±12.0)岁,都有心电图证实其阵发性心房颤动史,X线、心脏超声排除有心脏扩大,于窦性心律时进行SAECG检测。 2.SAECG的记录方法及测量指标:采用美国
Ventricular late potentials (Ventricular late potentials, VLP) and ventricular tachycardia, ventricular fibrillation and other malignant arrhythmias have seen a lot of reports. The signal averag electrocardiogram (Signal averag electrocardiogram, SAECG) technology to detect atrial arrhythmia rarely reported. In order to evaluate the value of SAECG in predicting the occurrence of atrial fibrillation in patients, the authors tested SAECG in normal subjects and patients with paroxysmal atrial fibrillation to investigate the relationship between SAECG and atrial fibrillation. 1. Subjects: 33 cases of normal group, 18 males and 15 females, aged 15-65 years (average 43.7 ± 12.8) years old, no history of heart disease, physical examination, electrocardiogram, X-ray and echocardiography showed no cardiac enlargement and other obvious Organic diseases and atrial arrhythmias. 19 cases of paroxysmal atrial fibrillation group, 13 males and 6 females, aged 28 to 69 (mean 49.7 ± 12.0) years of age, have confirmed the history of paroxysmal atrial fibrillation, X-ray, cardiac exclusion of cardiac enlargement SAECG was performed in sinus rhythm. 2.SAECG recording methods and measurement indicators: the United States
