The method for automatic analysis of micropotentials over the entire ECG recording has been developed and the results of measuring the energies of micropotentials in various amplitude-time intervals have been analyzed to assess the diagnostic value of the developed method. The paper presents the results of the study of micropotentials in a patient with atrial fibrillation of 4-year duration recorded by the nanosensor-based hardware and software complex in frequency range from 0 to 10,000 Hz, with a level of higher than 1 μV and a sampling rate of 64,000 Hz, whose sinus rhythm restored.

The most significant decrease in the energy of micropotentials by an order of magnitude or more was observed in the range of amplitudes (5.1–20) μV. The method can be employed for individual use and in hospitals for early detection of asymptomatic ischemia that often leads to sudden cardiac death.
