cardiovascular system the heart and blood vessels, by which blood is pumped and circulated through the body; see also circulatory system. CD system (cluster designation) a system for classifying cell-surface markers expressed by lymphocytes based on a computer analysis of monoclonal antibodies against...
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...

Previously, we demonstrated that the expression of the ATF3 gene is induced by many stress ...
In the primitive heart tube, all the cardiomyocytes are electrically coupled, and contractions proceed in peristaltic waves from the inflow to outflow. However, in the four-chambered heart, the conduction system paces and orients the contractions of the atria and ventricles to maximize cardiac outpu...
Mental stress could lead to augmentation of sympathetic system, catecholamine release which can lead to increase in the velocity of conduction in atria and influences on intraventricular conduction time by changing autonomic balance, which can lead to reduced QRS duration. Heart rate variability and ele...

Duplication or absence of parts of the specialized cardiac conduction system in patients with heterotaxy syndrome causes significant clinical disease, but the mechanistic basis by which embryonic disruption of left-right patterning alters conduction system patterning in these patients is not well understood...
The severity and location of conduction system abnormalities correlated with the severity and location of associated structural heart disease and were identifiable at the earliest stages examined. The Zic3 mouse model provides a novel tool to dissect the mechanistic underpinnings of conduction system ...
