Voltage clamp method on single cardiac cells from adult rat heart

A I Undrovinas et al. Experientia. .

Abstract

Voltage clamp experiments on isolated cardiac cells from adult rat hearts were carried out using an intracellular dialysis method. The fast inward current was recorded. Tetrodotoxin (TTX) at a concentration of 2.5 x 10(-7) g/ml blocked this current to 30% of its initial value. Inward maximal fast current density was calculated to be 0.14--0.7 mA/cm2.
