The atria provide an important contribution to cardiac function. 1, 2 Besides their impact on
ventricular filling, they serve as a volume reservoir, host pacemaker cells and important parts …

Optimal cardiac function depends on proper timing of excitation and contraction in various
regions of the heart, as well as on appropriate heart rate. This is accomplished via …

Rationale: Understanding atrial fibrillation (AF) requires integrated understanding of ionic
currents and Ca2+ transport in remodeled human atrium, but appropriate models are limited …

Triggers propagating into atrial myocardium may initiate reentering wavelets if the
wavelength is sufficiently short. Wavelength shortening can occur even in normal atria if the …

The aim of this review is to provide basic information on the electrophysiological changes
during acute ischemia and reperfusion from the level of ion channels up to the level of …

Na, K-ATPase plays a crucial role in cellular ion homeostasis and is the pharmacological
receptor for digitalis in man. Nine different human Na, K-ATPase isozymes, composed of 3 α …

Na+, K+-ATPase is ubiquitously expressed in the plasma membrane ofall animal cells
where it serves as the principal regulator of intracellularion homeostasis. Na+, K+-ATPase is …

Abstract Intracellular [Na+]([Na+] i) is regulated in cardiac myocytes by a balance of Na+
influx and efflux mechanisms. In the normal cell there is a large steady state electrochemical …

A family of small, single-span membrane proteins (the FXYD family) has recently been
defined based on their sequence and structural homology. Some members of this family …
