Abstract in different language:	The paper devotes to a developed wearable photoplethysmographic (PPG) sensor for human heart pulse monitoring. The sensor can work in a weak magnetic field with radiofrequency (RF) disturbance present during patient examination in the low field magnetic resonance imaging device. The experiments have confirmed the proper real-time functioning with safe wireless communication and data transmission between the sensor and the control device performing post-processing of the PPG signal and estimation of the signal properties (level threshold, ripple, range, etc.). The developed control application for Windows platform performs also signal filtering and heart rate (HR) determination. Influence of the used sampling frequency on the precision and stability of the finally determined HR values was analyzed, too.
