摘要 对32例昏厥患者进行信号平均叠加心电图检查。心室晚电位阳性10例,阳性检出率为31.25%。其中器质性心脏病7例,心室晚电位阳性4例,占57%。不明原因昏厥25例,心室晚电位阳性6例,占24%。其中20例经Holter或/和心电监护;将其分为室速室早组10例,心室晚电位阳性7例,非室速室早组10例,心室晚电位均阴性。两组差异有非常显著性(P<0.002)。所以心室晚电位检查对有器质性心脏病和室性心律失常所致昏厥病例的阳性检出率高。它是一项非创伤性检查方法,患者容易接受,因此可以作为昏厥患者的一项筛选试验。 The signal averaged electrocardiogram (ECG) study was performed in 32 patients with syncope attack. The patients (31.25%)showed ventricular late potential on signal averaged ECG, 7 of them suffered from organic heart disease, and 4 out of the 7 (57%) showed ventricular late potential. Among 25 patients with syncope of unknown cause, 6 (24%) showed ventricular late potential. Twenty patients had undertaken Holter or/and electrocardiographic monitoring; 7 of 10 in group of ventricular tachycardia and ventricular premature beats showed ventricutar late potential, and 10 in group of non-ventricular tachycardia and non-ventricular premature beats showed no ventricular late potential (P<0.002). Thus the signal averaged ECG examination is beneficial to study of patients with organic heart disease and ventricular arrhythmia. The high rate of detecting late potential, and the non-invasive method is easily acceptable. Thus signal averaged ECG is worthy to be performed in syncope patients as screening test.
