AbstractNon-invasive cardiac examination in standard clinic is still using 12-lead electrocardiograph. The results of the examination are presented on ECG paper or on the monitor screen. A normal electrocardiogram on one lead is not necessarily normal for the other lead, because each lead represents a certain part of the heart so that one by one is necessary. This examination takes time so that it can increase the stage of the disease if the patient turns out to be in an abnormal condition. This paper aims to correlate the peak amplitude of each lead to normal and abnormal heart conditions. If it is known that the peak amplitude is correlated between the leads, the other leads do not need to be checked, so that the diagnosis time will be obtained faster. Cardiac biosignal data that has been sampled with a frequency of 250 Hz is a discrete signal that can be stored digitally in a database. 10 samples of normal conditions and 10 samples of abnormal conditions were analyzed using Saphiro-Wilk so that the data were normally distributed. Spearman correlation analysis is used to get peak amplitude correlation between leads. The results showed that for abnormal conditions with a significance of 0.01 there was a correlation between the peak P lead I with leads III and V5, while for normal conditions there was a correlation between peak P lead I and leads V3 and V4. In abnormal conditions there is a correlation between peak R lead II and V6, while in normal conditions there is a correlation between peak R lead I and aVF.
