    New recording setup for ratiometric recording of action potentials by optical means

  • Original language description

    Monophasic action potential (MAP) can be recorded from the heart surface by optical method via fluorescence measurement. The motion of isolated heart during experiment caused additional noise in recorded signal. The motion artifact can be eliminated by ratiometric fluorescence emission measurements. This study is based on experiments in which a new ratiometric recording setup is used for recording MAPs from isolated rabbit hearts perfused according to Langendorff. MAPs recorded by new ratiometric recording setup are compared with simple optical MAP measurement without ratiometry.

    Nové snímací zařízení pro ratiometrickou registraci akčních potenciálů optickou metodou

  • Czech description

    Monofázické akční potenciály (MAP) lze snímat z povrchu srdce optickou metodou pomocí měření fluorescence. Pohyb izolovaného srdce během pokusu způsobuje dodatečný šum ve snímaném signálu. Pohybový artefakt lze odstranit ratiometrickým měřením fluorescenční emise. V této studii jsme využili tento způsob registrace pro snímání MAP na izolovaných srdcích králíka perfundovaných dle Langendorffa. Potenciály byly porovnávány se signály získanými prostou optickou metodou bez ratiometrie.
