title: [A new technic for recording cardiac action potentials. Laser spectrometry].
abstract: The new technique described rests on analysis of the fluorescence emitted by a potential-sensitive dye after excitation by a laser light of suitable wavelength. This technique, which requires no physical contact with tissues, should also be applied to the study of surface activation, using more potent pulsed laser rays and video methods.
