The conduction method in the heart is responsible for making electrical alerts that induce the heart to contract and chill out.
The sinoatrial node, also called the pacemaker, polarized heart is responsible for placing the heart’s rhythm. The wave of depolarization that originates through polarized heart the SA node is answerable for resulting in the atria to agreement.
Depolarization is the procedure by which the cells on the heart come to be much less damaging and agreement. When the cells are at relaxation, They can be negatively charged or polarized.
