We consider the development of electrocardiography on time to the birth of our days. Describe the work and re-searchers to ensure a substantial development of electrocardiography. Among them Sharpie, Einthoven, Wilson, butchers, at al. Shows the main achievements in the history of electrocardiography. A modern method of electro-cardiography is analyzed. The basic trend of its development is showed. A method for large-scale electrocardiography, high resolution electrocardiography and high-frequency electrocardiography is described. Describes an ultrahigh resolution electrocardiography method proposed by the authors. Considered in detail the issues of circuit and algorithmic of primary and secondary processing ECG-signal with ultra-high resolution. The scheme of analog processing of dual-channel ECG-signal with each leads and special scheme of the primary digital processing is developed. The problem of accurate determination of characteristic points of ECG-signal related to ensuring the syn
