<p>Signal travels down to the ventricles through the Bundle of His and finally to the Purkinje Fibers causing Ventricular contraction/depolarization followed by the relaxation of the ventricles. If there is an issue in this system we can have arrhythmia like Afib, AF, SVT etc. Understanding normal cardiac anatomy and physiology is an important component of performing ACLS. The heart is a hollow muscle comprised of four chambers surrounded by thick walls of tissue (septum). The atria are the two upper chambers and the ventricles are the two lower chambers. The left and right halves of the heart work together to pump blood throughout the body. On the RIGHT side ( Takes blood RIGHT to the lungs )-The right atrium (RA) and the right ventricle (RV) pump deoxygenated blood to the lungs where it becomes oxygenated. On the LEFT side ( Gets blood that LEFT the Lungs )-This oxygen-rich blood returns to the left atrium (LA) and then enters the left ventricle (LV). The LV is the main pump that delivers the newly oxygenated blood to the rest of the body.
