Electrocardiograms
ElectrocardiogramsThe electrical activity of the heart is a useful indicator of how well the heart is functioning. Muscle cells possess an inherent electrical activity that is necessary to their function. Because the heart is a large mass of muscle cells, the resulting composite picture of the electrical activity of that mass is a clinically useful piece of information.The composite electrical activity that results from the action of the total number of cardiac muscle fibers results in a signal that can be approximately represented by a vector quantity. Imagine for a moment, the electrical field that would be generated on the surface of the body as a result of a battery "spinning" in 3-D space inside your body. In this vector model, the heart is an electric dipole locate…
