The effect ofisoprenaline (IS O; 5-10-8 to I 0 6 M) on active Na transport was studied in depolarized sheep cardiac Purkinje fibres. Membrane current (/) and intracellular Na activity were measured simultaneously during enhanced Na pumping in voltage clamped preparations. ISO stimulated enhanced act
The aim of the present study was to advance our knowledge regarding the anatomy of the purkinje fibres from their origin, at the bundle branches, till their termination within the myocardium. Indian ink injections of the purkinje fibres were carried out in the left ventricle of 25 fresh sheep heart
The effects of the cardioplegic solution HTK on membrane potential (EM) and intracellular K and Na activities (a~, a~a) were studied in sheep cardiac Purkinje fibres by means of conventional and ion-selective microelectrodes. HTK contains (raM): Na 15, K 10, Ca 0, Mg 4, histidine 180. (1) In control
