These results suggest that the classical solid angle theory provides a useful approximation of the ST-segment deflection in very acute ischemic phase, until development of the intraventricular conduction delay. 展开 关键词: Myocardium Heart Conduction System Pericardium Animals Dogs Myocardial Infarction ...
The heart contains structures consisting of atypical muscular tissue, the cells of which are poor in myofibrils and rich in sar-coplasm. The atypical muscular tissue forms the conduction system of the heart, which includes (1) the sinoatrial node, located in the wall of the right atrium, betw...
In the heart, the vectors associated with the patterns of contraction are determined by the sequence of depolarization. In order to alter this sequence, the conduction system of 12 normal dogs was interrupted by the production of complete atrioventricular block. After 3 months of electronic pacing ...
To repair congenital heart defects by means of open heart surgery, the surgeon needs guidance about the location and distribution of the specialized conduction tissues, in order to avoid their direct damage and consequent conduction disturbances. This review addresses the historical steps of the morphol...
(remote, infarct, and graft) at 12 weeks showed significant expression of the protein in the graft as compared to the infarction site (p-value < 0.05) (Fig.2j). As Cx43 regulates intercellular coupling and conduction velocity, the results suggest that the human grafts continue to ...
With this power, which he calls “conduction,” in his grasp, Hiram is determined to make his escape — and to take as many of the Tasked with him as he can.47. Ninth House by Leigh Bardugo (October 8) Buy on Amazon Add to library YA stalwart Leigh Bardugo makes her adult ...

*p<0.05. Tibiae were measured using a PIXImus system (GE-Lunar). B) Scatter-plot of heart weight vs tibial length. Note that the tibiae of wild-type mice did not grow post-maturation. However, the tibae of Ames mice continued to grow beyond 6 months of age. C) Heart weight/Tibial ...
In this study we quantified the electrophysiological effects of both isomers of propranolol on the conduction and pacemaker system of the heart. The experiments were performed on isolated hearts using a special ECG recording and stimulation technique. To abolish isoproterenol's beta adrenergic stimulatory...
In addition to the morphogenetic events leading to the morphogenesis of the heart, two additional events are equally critical during cardiogenesis: (a) the development of the electrical wiring of the heart, i.e., the cardiac conduction system, and (b) the formation of an irrigation system, i...
