In canine experiment, the averaging of high right atrial electrical activity revealed the pre-A preceding the atrial deflection, which was proven to be a part of the electrical activity of sinus nodal region. 2) The pre-A was obtained in 114 (75%) of 153 clinical cases. 3) The mean pre-A interval was 18 +/- 4 msec in control group, and was prolonged in cases with sick sinus syndrome, ischemic heart disease and myocarditis. 4) The significant correlation existed between the pre-A interval and the SACT by Strauss' method (r = 0.80, p < 0.01). 5) The pre-A obtained by averaging technique is relatively simple, safe and reliable method, and is useful for evaluating the sino-atrial function.

在犬类实验中，对右心房高电活动进行平均处理后发现，心房波之前存在前A波，经证实它是窦房结区域电活动的一部分。2) 153例临床病例中有114例（75%）检测到前A波。3) 对照组的平均前A间期为18±4毫秒，在病态窦房结综合征、缺血性心脏病和心肌炎患者中该间期延长。4) 采用施特劳斯法测定时，前A间期与窦房结恢复时间之间存在显著相关性（r = 0.80，p < 0.01）。5) 通过平均技术获得的前A波是一种相对简单、安全且可靠的方法，有助于评估窦房结功能。
