New technologies of recording and processing of electrical cardiac potentials made significant advances in the course of recent years, contributing to the production of instrumentation the application of which enables a high level of diagnostics, therapy and rehabilitation to be reached in internal medicine. Modern technology of recording potentials by means of vacuum electrodes with surface finish and simultaneous application of new adaptable filters enable a more accurate digital processing of electrical pulses and a higher quality of their recording, indication, transmission, interpretation and archiving. The given requirements are complied with especially by new polyfunctional instruments, made e.g. by the firm SCHILLER AG, and some specialized devices of other producers, serving, among others, for examination of heart rate and its variability. New technical devices, applied sensibly and economically, should be accessible in the near future also to peripheral cardiologic and internal centres.
