The heart conduction system is made up of cells, nodes, and signals that help your heart to beat. In fact, the cardiac conduction system is responsible for our heart beating around 2.5 billion times during the average human lifespan. The conduction system, also called the cardiac electrical sy...
In addition to the taste and vestibular cells, OTOP1 is also detected in brown adipose tissue, the mammary gland, and the heart2,10. In contrast, OTOP2 is expressed in the stomach, testis, and olfactory bulb, whereas OTOP3 is present in the epidermis, small intestine, stomach, and ...
The present study aims to introduce an automated CV calculation method, based on isochronal activation timings, which helps to better identify areas of slower conduction displayed on a 3D electro-anatomic map (EAM) of the heart chambers during atrial and ventricular arrhythmias. 1 3Vol.:(...
of laterally spaced conductive paths (16) wherein the method includes the steps of applying an adhesive (22) including a resin having a twenty to twenty-five percent by weight content of conductive metal particles over the mounting surface (14) of the substrate (12) having the conductive ...
heart development1, mice lacking ET-1 receptors were viable and they did not reveal any VCS abnormalities7. Interestingly, Nrg-1 but not ET-1 treatment increased the expression of a VCS specific reporter gene expression in E9.5 mouse embryos cultured for 48 hrs3. Inability of Nrg-1 to ...
Normal heart function is critically dependent on the timing and coordination provided by a complex network of specialized cells: the cardiac conduction system. We have employed functional assays in zebrafish to explore early steps in the patterning of the conduction system that previously have been ...
Enhanced imaging techniques have provided great insight into the CCS components and changes with disease that can contribute directly to our understanding why the heart beats, diagnostic development, therapeutic, pharmacological and surgical methods, and the improvement of computational modelling studies. ...
Heart problems due to poor electrical conduction or loss of heart muscle mass, resulting in low heart rate and blood pressure or an irregular heart beat beijing.ufh.com.cn 由于导电性差 或心脏肌肉量减少而引起的心脏问题,可能造成心率低、血压低或心跳不规律 beijing.ufh.com.cn...
The heterogeneity of functional cardiomyocytes arises during heart development, which is essential to the complex and highly coordinated cardiac physiological function. Yet the biological and physiological identities and the origin of the specialized cardiomyocyte populations have not been fully comprehended. ...
The apex to base conduction was measured as the longitudinal conduction of the heart, which is presumably mediated by gap junction channels. Mice after varying treatments were anesthetized 2,2,2-tribromoethanol (200 mg kg−1, i.p.). Hearts were then quickly excised and placed in ice...
