It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
