Recently, signal-averaging technique of high resolution electrocardiogram to detect electrical activity from the region of the bundle of His has developed. But this technique has not been commonly used for detection of His bundle activity, compare it with detection of late potentials. We studied suitable lead system, filters, signal averaging counts and high resolution gain to detect surface recording of His bundle activity. We also studied that if we recorded electrogram using late potential detection system, how many people could be detected for His bundle activity. Signal-averaging technique of high resolution electrocardiogram clinically applicated especially in atrio-ventricular block patients. There were significant changes in the frequency of identifying His bundle activity by signal-averaging electrocardiographic system recorded by varying leads system, filters, averaging counts, high resolution gain. When using this technique in a clinical situation, we should use most appropriate device, including its condition.
最近，用于检测希氏束区域电活动的高分辨率心电图信号平均技术已得到发展。但与检测晚电位相比，该技术尚未普遍用于检测希氏束活动。我们研究了用于检测希氏束活动体表记录的合适导联系统、滤波器、信号平均次数和高分辨率增益。我们还研究了如果使用晚电位检测系统记录心电图，能检测出多少例希氏束活动。高分辨率心电图的信号平均技术在临床上尤其适用于房室传导阻滞患者。通过改变导联系统、滤波器、平均次数、高分辨率增益记录的信号平均心电图系统识别希氏束活动的频率有显著变化。在临床应用该技术时，我们应使用最合适的设备，包括其状态。
