• 7 Differences in action potential characteristics, similar to those described in syncytial preparations, have also been found in single myocytes isolated from the epicardium, M region, and endocardium of the canine ventricular free wall. (ahajournals.org)
  • Maximal oxidative capacity (V Max ) and relative contributions of the respiratory chain complexes II, III, IV (V Succ ) and IV (V TMPD ), mitochondrial content (citrate synthase activity), coupling, NO (electron paramagnetic resonance), and reactive oxygen species (ROS) production (H 2 O 2 and dihydroethidium (DHE) staining) were determined in rat sub-endocardium (Endo) and sub-epicardium (Epi).

  • This study validated a new noncontact multielectrode array catheter and accompanying analysis system to provide electroanatomic mapping of the entire left ventricular (LV) endocardium during a single beat. (ahajournals.org)
  • Principal component analysis was computed to describe the statistical variability of the SSMs, which were then deformed by applying an active shape model (ASM) approach to segment the LV endocardium in CMR images of 45 patients. (uzh.ch)
