The paper presents the preliminary study of the utilization of a low resolution ECG signal analysis. The analysis was performed on the signals obtained from a hand-held ECG monitor usually used in primary health care. The aim. The main aim of the study was a registration of series of data by volunteers within couple of months and determination of signal quality and main ECG parameters as follows: Q, R, S waves, QRS duration as well as the end of PQ and the beginning of ST segment. Additionally, the heart rate variability was determined. Materials and methods. The data was registered by 12 volunteers aged from 35 to 55. The ECG tests were carried out for 7 months. The sample rate of the signal was 100 Hz. To determine the ECG parameters the signal processing and statistical methods was used. Results. The sensitivity of the following ECG parameters were: R wave detection - 99,2 %, Q wave detection - 99,1 %, S wave detection - 99,0 %, QRS duration - 99,2 % respectively.
