We present the results on the design, production and preliminary experimental testing of the multichannel magnetocardiography (MCG) device. Such a supersensitive device is intended for examination of the patients with cardiology diseases and investigation of the electrophysiological processes in a human heart and in Ukraine was developed for the first time. Device possesses 8 channels including 4 signal ones for measurements of the magnetic fields originated from the heart currents, 3 reference channels measuring the magnetic environmental noise, and 1 reference electrocardiography (ECG) channel. As a magnetic field sensor the supersensitive cryoelectronic magnetometer developed at the Glushkov Institute of Cybernetics (Kyiv) and based on a superconductive quantum interference devices (SQUIDs) operating at ultra-low liquid helium temperature (4,2 K) was used. Data acquisition is fulfilled via ADC using the on-line adaptive noise compensation technique. Testing of the device has shown the better signal-to-noise ratio (SNR) in comparison to single-channel MCG device. Installation of the developed advanced medical instrumentation is planned to be performed at the Strazhesko Institute of Cardiology (Kyiv) within the framework of the project supported by the Science and Technology Center in the Ukraine (STCU)
