Effect of prolonged depolarizations on twitch tension and intracellular sodium activity in sheep cardiac Purkinje fibres.

1. Twitch tension and intracellular Na+ activity (aiNa) were measured in voltage-clamped sheep cardiac Purkinje fibres. aiNa was measured using Na+-sensitive micro-electrodes filled with the liquid ion exchange resin. ETH 227. The stimulus for contraction was a constant 200 ms depolarizing pulse to...
