心电图是被记录在布满大小方格的纸上，所以想要知道心电图怎么看，首要的是知道这些格子代表的意义。这些方格中每一条细竖线相隔1mm，每一条细横线也是相隔1mm，它们围成了1mm见方的小格。粗线是每五个小格一条，每条粗线之间相隔就是5mm，横竖粗线又构成了大方格。

心电图记录纸是按照国际规定的标准速度移动的，移动速度为25mm/s，也就是说横向的每个小细格代表0.04s每两条粗线之间的距离就是代表0.2s。

国际上对记录心电图时的外加电压也是有规定的，即外加1mV电压时，基线就应该准确地抬高10个小格，也就是说，每个小横格表示0.1mV，而每个大格就表示0.5mV，每两个大格就代表了这1mV。
