介绍约瑟夫、沃塔克(Joseph Wartak)报道的一种简便分析儿科心电图振幅的透明图尺如下.这种图尺比目前使用的正常值表方便得多,它的主要优点是:(1)减轻了医生记忆小儿QRS波正常值的负担,无需测量QRS波振幅,并可节省阅读心电图的时间;(2)使学习儿科心电图变得较为容易.因为据粗略估计,数字资料占组成儿科心电图诊断项目的一半;(3)尤其适用于非专职从事心电图工作的临床医生及繁忙的儿科门诊.图尺使用方法简单,按以下两步进行(见附图):(1)以图尺上适当年龄范围的QRS图形放于该儿童相应导联有代表性的QRS波上;(2)图尺上QRS图形的基线应与心电图上QRS波基线对准.如果心电图上R或S波
Introducing Joseph Wartak An easy-to-see transillumination scale for pediatric ECG amplitude is as follows, which is much more convenient than the currently used normalized list and has the following major advantages: (1) The physician can remember the burden of normal QRS wave in children without measuring the QRS wave amplitude and saving the time of reading the ECG. It is easier to learn the pediatric cardiogram because it is roughly estimated that the digital data make up the pediatric ECG diagnosis item (3) It is especially suitable for clinicians and busy pediatric clinic who are not part-time in ECG work. The method of using the scale is simple, follow the following two steps (see the attached drawings): (1) Take the appropriate age range Of the QRS pattern is placed on the QRS wave representative of the corresponding lead of the child; (2) the baseline of the QRS pattern on the ruler should be aligned with the QRS wave baseline on the electrocardiogram If the R or S wave
