Low K+ current in arterial myocytes with impaired K+-vasodilation and its recovery by exercise in hypertensive rats

K + channels determine the plasma membrane potential of vascular myocytes, influencing arterial tone. In many types of arteries, a moderate increase in [K + ] e induces vasorelaxation by augmenting the inwardly rectifying K + channel current ( I Kir ). K + -vasodilation matches regional tissue activ...
