14.   General information about the Heart and ECG Measurements 

The heart is a muscular pump controlled by electrical impulses generated by the body. It 
is divided into two sides by the septa. Each side has two chambers –an atrium and a 
ventricle-linked by a one-way valve. The left atrium and ventricle control oxygenated 
blood, and the right atrium and ventricle control de-oxygenated (“used”) blood. 

The electrical impulse that causes the heart to beat spreads across the atria, causing 
the left and right atrium to contract and pump blood into the left and right ventricles 
respectively. The two ventricles then contract and pump blood out of the heart. The heart 
muscle then relaxes, or re- polarizes, allowing blood to fill up the heart again.
