Atrial metabolism and tissue perfusion as determinants of electrical and structural remodelling in atrial fibrillation.

abstract：:By measuring the coronary sinus blood flow using the thermodilution technique the influence of "thermodilution catheter" withdrawal from the great cardiac vein to the ostium of the coronary sinus was investigated in 41 patients. In addition, the influence of normal and forced respiration on coronary sinus blood flow w...

abstract：OBJECTIVE:Cardiac energetics and performance depend on the expression level of the fast (alpha-) and slow (beta-) myosin heavy chain (MHC) isoform. In ventricular tissue, the beta-MHC isoform predominates, whereas in atrial tissue a variable mixture of alpha- and beta-MHC is found. In several cardiac diseases, the slow...
