Summary:Today are used electrocardiograms with sensors, which require a wild-sprays to ensure electrical contact between sensor and skin. Such devices are for set to time-consuming and problematic for long term record. The lack of principle eliminates the use of non-contact sensing. The object was to construct such an ECG device, which has been designed and constructed under the project. On the other hand, non-contact sensing is burdened by relative high level of noise in the useful signal what is not suitable for medical purposes. This paper is focused just on issue of removing noise from the signal obtained from non-contact device. The aim is proposal of processing these signals, which is suitable for the another analysis. The aim is filtered ECG signals using suitable methods of linear filtering obtained from the non-contact device from the mains and battery. The aim is also to find signals that are suitable for medical purposes obtained from experiments involving the device. The results clearly show the noise reduction in ECG signals using low pass, high pass and notch filters.
