Summary:
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.
Key words:
