Altered Excitation-Contraction Coupling in Human Chronic Atrial Fibrillation.
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory period, depressed intracellular Ca2+ transient, and reduced myocyte contractility. Here we summarize the current knowledge of the ionic bases u...
متن کاملTransmural heterogeneity and remodeling of ventricular excitation-contraction coupling in human heart failure.
BACKGROUND Excitation-contraction (EC) coupling is altered in end-stage heart failure. However, spatial heterogeneity of this remodeling has not been established at the tissue level in failing human heart. The objective of this article was to study functional remodeling of excitation-contraction coupling and calcium handling in failing and nonfailing human hearts. METHODS AND RESULTS We simul...
متن کامل1 [ Na ] handling in the failing human hearti
Proper contractile function of the heart depends on intact excitation–contraction processes and ion homeostasis of the myocytes. The 21 21 1 Ca ion activates contraction through its binding to troponin C. However, Ca homeostasis is tightly linked to Na regulation because 21 1 21 21 the primary mechanism for Ca efflux in cardiac myocytes is via electrogenic Na /Ca -exchange. While altered Ca -ho...

To complete your curiosity, we offer the favorite excitation contraction coupling in skeletal cardiac and smooth muscle book as the choice today. This is a book that will show you even new to old thing. Forget it; it will be right for you. Well, when you are really dying of excitation contraction coupling in skeletal cardiac and smooth m...
متن کاملAltered cardiac excitation-contraction coupling in ventricular myocytes from spontaneously diabetic BB rats.
Cardiac excitation-contraction (E-C) coupling abnormalities in chemically induced diabetes have been well defined. Heart dysfunction has also been reported in diabetes of genetic origin. The purpose of this study was to determine whether heart dysfunction in genetically predisposed diabetes is attributable to impaired E-C coupling at the cellular level. Myocytes were isolated from 1-yr-old BioB...
