The torsional behaviour of the heart (i.e. the mutual rotation of the cardiac base and apex) was proved to be sensitive to alterations of some cardiovascular parameters, i.e. preload, afterload and contractility. Moreover, pathologies which affect the fibers architecture and cardiac geometry were...
The apex beat was located to the 4th intercostal space, mid-clavicular line; percussion suggested a normal area of cardiac dullness. There was neither pericardial nor pleural friction rub and no cardiac murmurs. Pericarditis as initial clinical manifestation of systemic lupus erythematosus in a girl ...
MHCCre/ChR2-tdTomato (MHC-ChR2) hearts show uniform responsiveness to photostimulation with blue light in all four chambers (LA, RA, LV, RV) of the heart, and all 6 subregions of the heart, with each ventricle separated into its base and apex (Fig. 6a). However, DbhCre/ChR2-td...
H2O2release during mitochondrial state 3 respiration and maximal respiratory capacity in control mice and mitoNEET KO mice at 3 months (a;n = 6 each) and 12 months of age (b;n = 5 each). Representative immunoblot and summary data of HNE protein levels in the heart from control ...
For 32 animals of a mean age of 4.7 years, the recordings of the 12 leads (I, II, III, aVR, aVL, aVF, CV6LU, CV6LL, CV6RL, CV6RU, V10 and base-apex) were m... L Deroth - 《Canadian Veterinary Journal La Revue Veterinaire Canadienne》 被引量: 81发表: 1980年 Abnormalities...
The automatic segmentation method uses a statistical SD-model, inspired by Active Shape, which locates the base and apex automatically from a cardiac scintigram. Key features of this algorithm are that it tan handle cases where there is no or very little activity in the apex and also if ...
For example, whole cell recordings from isolated rabbit ventricular myocytes demonstrate apex-base differences in left ventricular APD (Cheng et al., 1999). Considerable regional heterogeneity in the duration of monophasic APs recorded from the endocardial surface of pig and human hearts has also ...
On the lateral view, ratios between the length of the heart from base to apex and total length of the carina were calculated. On the ventrodorsal view, ratios between the width of the heart at its widest point and the distance between the ribs at the same level and between the width of...
