Effect of repetitive activity upon intracellular pH, sodium and contraction in sheep cardiac Purkinje fibres.
1. The influence of repetitive activity upon intracellular pH (pHi), intracellular Na+ activity (aNA(i)) and contraction was examined in isolated sheep cardiac Purkinje fibres. Ion-selective microelectrodes were used to measure intracellular Na+ and H+ ion activity. Twitch tension was elicited by fi...
