<b></i>Abstract : </b><i><p align=\"justify\"> <br /> This thesis describes the development of the PC based system for application in medical instrumentation, to measure the biopotential of heart. The instrument called electrocardiograph and in this thesis called PC-ECG. <br /> <br /> The developed system consists of hardware and software. The hardware called ECG-modul, place in the external of the PC, communication betwen of them are used printer port (LPT). ECG-modul consists of: interface and data switch, instrumentation amplifier, filter and analog to digital converter, buffer amplifier and analog switch, and isolated power supply. <br /> <br /> The program has been developed consists of. display, data acquisition, signal processing, data base, and QRS detector. The language used to development all of the program are: C (Turbo C V-2.0) and C++ (Borland C++ Builder V-1.0). The program was developed, work under Windows\'95 and interaction with the user, use the graphical user interface (GUI) concept. <br /> <br /> Standard measurement in this research is the clinical 12 leads standard, with ten electrodes. Total direct measurements for this instrument are eight, i.e: standard lead I and III, and chest lead Cl until C6. The other leads, ie: aVL, ON, aVR and lead II, are obtained from calculation. The electrodes used the surface type. <br /> <br /> Laboratory tests were done in Medical Electronics Laboratoty, LABTEK VIII-ITB and Hasan Sadikin Hospital, departement of Instalasi Perawatan Sarana Rumah Sakit (IPRS). The result from both laboratory were encouraging although further refinements are still required.
