CHAPTER 2 2.1 ELECTROCARDIOGRAM The ECG Signal is a graphical representation of the electromechanical activity of system. The various propagation action potentials within the heart produce a current flow, which generates an electrical field that can be detected, in significantly attenuated form, at the body surface, via a differential voltage measurement system. The resulting measurement, when taken with electrodes in standardized locations, is known as the electrocardiogram. The ECG signal is…

Heart failure is when the heart is too weak to pump blood efficiently, and cannot provide proper cardiac output that the body needs to maintain the body’s metabolic needs. Also, heart failure is when the heart muscle has become damaged and cannot contract and pump blood up and through the valves and out through both sides of the heart or the heart muscle has become too stiff. This process mainly relates to the heart muscles of the ventricle chambers. The ventricles are the main problem within…
