[Study of electro-mechanical coupling in heart fibers by an optical method]
Abstract:
It has been shown on frog auricle fibres that optical recording of contraction related to the action potential or ionic currents allows to distinguish between phasic (concerned with calcium current coming into the cell) and tonic (concerned with Ca++ input through Na/Ca metabolic diffusion) contraction components and to investigate the regulation of these components by compounds.
