A PC-Based EKG Machine is a device which performs a diagnostic test that checks the electrical activity of your heart. An EKG translates the heart's electrical activity into line tracings on paper. The spikes and dips in the line tracings are called waves. The heart is a muscular pump made up of four chambers. Med-Resource offers PC-Based EKG Machines to doctors nationwide!
