Witryna28 maj 2024 · The action potential originates in the sinus node cells, propagates through the whole heart via an active electrophysiological process called impulse conduction, and can be measured as the electrical potential difference between the intra- and extracellular space. The stimulus spreads through both atria, causing their contraction. WitrynaHeart in Motion is the ninth studio album by Christian singer-songwriter, Amy Grant, released on March 5, 1991. Unlike Grant's previous albums, Heart In Motion contains …
