When your alive does brain ever stop sending electricity to heart?

No, as long as you are alive, the brain never stops sending electricity to the heart. The brain's electrical signals control the heart's rate and rhythm, ensuring a continuous supply of oxygen-rich blood to the body's tissues and organs. This electrical conduction pathway involves specialized structures such as the sinoatrial (SA) node, the atrioventricular (AV) node, and the bundle of His, which work together to generate and transmit the electrical impulses that cause the heart to contract and pump blood.
