Potassium channel currents are important in maintaining the normal electrical activity in
most excitable cells. This family of channels controls the cell resting potential and action …

The development of novel drugs specifically directed at the ion channels underlying
particular features of cardiac action potential (AP) initiation, recovery, and refractoriness …

This paper is the outcome of the fourth UC Davis Systems Approach to Understanding
Cardiac Excitation–Contraction Coupling and Arrhythmias Symposium, a biannual event …

Cardiac K+ channels are membrane-spanning proteins that allow the passive movement of
K+ ions across the cell membrane along its electrochemical gradient. They regulate the …

K+ channels in heart can be subdivided into two groups, voltage-operated and ligand-
operated channels. Only the voltage-operated channels—i K, i to, and i K1—and one ligand …

Cardiac K+ channels are cardiomyocyte membrane proteins that regulate K+ ion flow across
the cell membrane on the electrochemical gradient and determine the resting membrane …

This is the second of the two White Papers from the fourth UC Davis Cardiovascular
Symposium Systems Approach to Understanding Cardiac Excitation–Contraction Coupling …

Potassium channels are membrane receptor sites for various drugs in the field of
cardiovascular diseases. These channel proteins are extremely diverse, not only as regards …

Potassium channels (K+) are membrane-spanning proteins which serve many important
functions and are becoming a hot topic in physiology. K+ channels determine or modulate …

Prolongation of action potential duration is the most consistent electrophysiological
abnormality in myocardium and myocytes from hypertrophied and failing hearts …
