Heart monitoring is needed in order to know the patient’s heart condition. In monitoring, storage media of heart monitor result is needed in order to help doctors and paramedics examine the patients. Therefore, a research to plan and create logger data system of heart signal as a modification of electrocardiograph was conducted. This research used amplifier, active High Pass Filter, active Low Pass Filter, Noch Filter, summing adder, and Microcontroller, and Delphi 7 Software to make interface program on personal computer. Heart Rate score (BPM) on 2x16 LCD indicated final error of 2,8%. Meanwhile, the final error of Software module was 1,4%. The measurement of lead II R signal amplitude resulted the final error of -4,5% and the final error on the distance length from R to R was -1,1%. Heart Rate score (BPM) with two human samples indicated error on sample one on sitting position of -3,8% and on sample two -6,3%, Sample one on Standing Position 2,9% and sample two -4,1%, Sample one on Roll Call -1,7% and sample one -8,4% and sample one on running in place -4,6% and sample two 4,1%. The result reading on Delphy 7 Software the errors were -0,3% on sample one and -6,5% on sample two. On standing position, sample one was -0,6% and sample two -2,2%, roll call position for sample one 1,7% and sample two -8,4%, and running in place for sample one 4,1% and sample two 3,3%. The score of R signal amplitude and the distance length from R of R on human sample indicated error for amplitude in sitting position -9,6%, standing -1,3%, roll call -3,0%, running in place -5,9%. The error on distance from R to R on sitting position was -5,9%, standing -17,3%, roll call 6,7%, and running in place 13,8%.
