Design of Portable Electrocardiograph Using 3-Electrodes with Lead II

摘要

Cardiovascular disease is one of the main causes of human deaths worldwide, then research on electrocardiograph (ECG) is increasingly growing. Based on the existing research which still have deficiencies that the signal obtained do not meet the criteria for can be analyzed or diagnosed. So the result of this architecture is a tool that is able to detect the electrical signals of the heart at the time required so that these modules have the capability of saving data the number of heart beats in one minute (BPM) via SD-Card with the format. CSV data ECG graph or read through the computer with the application so the figure graph delphi7 can be stored in the form of .bmp. For the results of the calculation equations and measurement on each circuit block of signal processing have almost the same value so that, the signal of the heart's fiber obtained by the appropriate form and the measurement result from the whole storage system of ECG graph in the module has error value for BPM of 0.33% and the Voltage equal to 0.08%. After the module testing is done, the specification modules are obtained as follows maximum BPM storage at 120BPM and the scale of ECG signal readings on module 5mm/mVs for Voltage (amplitude), 20mm/mVs for speed (Rate).
