[A method for the rapid pick-up of bioelectric potentials from the unprepared body surface of animals, with special reference to cardiac action potentials].

Established methods of obtaining cardiac action potentials indirectly are laborious and require much time and apparatus. A rapid method of picking up bioelectrical potentials from the intact body surface was developed by using rapid-contact proximity electrodes and a simplified conduction technique. Useful cardiograms were obtained without changing the normal posture of the animal.
