20.500.12556/DKUM-45672 IZDELAVA ELEKTROKARDIOGRAFA IN DIAGNOSTIKA POTENCIALNIH OBOLENJ SRCA DESIGN OF AN ELECTROCARDIOGRAPH AND DIAGNOSIS OF POTENTIAL HEART DISEASES V diplomski nalogi je opisan razvoj in uporaba tri-točkovnega elektrokardiografa, s katerim merimo razlike potencialov napetosti na telesu, ki jih povzroča srce v svoji okolici. Predstavljeno je osnovno delovanje srca ter predstavitev srca kot električni dipol, s katerim opisujemo povzročene potenciale. Elektrokardiograf je izdelan iz analognega in digitalnega dela vezja ter programskega vmesnika na računalniku, s katerim opazujemo zajet signal ter izvajamo diagnostiko potencialnih obolenj srca. V analognem delu se soočamo z zajemanjem izmeničnega signala, ki je izredno majhne amplitude, ki je superponiran na razmeroma visok enosmerni signal. V digitalnem delu pa se soočamo s pretvorbo analognega signala in komunikacijo z računalnikom. K digitalnemu delu lahko pripišemo tudi razvoj programskega vmesnika, ki omogoča interpretacijo signala na zaslon in diagnostiko. Tako za analogni kot digitalni del smo opisali razvoj, delovanje in uporabo. This diploma work describes the development and usage of three-point electrocardiograph which measures differential potential on the body caused by the human heart. Presented is the basic activity of the heart and the heart itself as an electric dipole which we use to describe caused potentials. Electrocardiograph consists of an analogue and digital part of the circuit, as well as the computer interface which we use for displaying data and diagnosing potential heart diseases. In the analogue part of the circuit we are measuring an AC signal of very low amplitudes considering the DC signal with very high amplitudes where AC signal and DC signal are superimposed. In the digital part of the circuit, however, we are dealing with an analogue-to-digital conversion and communication with the computer. The digital part deals also with the development of visual interface for displaying and diagnosing potential heart diseases. The activity, development and the use are presented for both parts of the circuit. elektrokardiograf EKG diagnostika obolenja srce Electrocardiograph ECG Diagnostics Conditions Heart true true false [G.
