Developmental transition depends upon hemodynamic ventricular loading

Published in Medicine and Law Weekly, September 23rd, 2005

A recent report describes optical mapping of electrical activation in the developing heart.

According to scientists in the United States, "Specialized conduction tissues mediate coordinated propagation of electrical activity through the adult vertebrate heart. Following activation of the atria, the activation wave is slowed down in the atrioventricular canal or node, after which it spreads rapidly into the left and right ventricles via the His-Purkinje system (HPS). This results in the ventricles being activated from the apex toward the base, which is a hallmark of HPS function."
