Above and beyond just the ECG or EKG machine itself, there are a lot of components necessary to ensure that the device works properly and helps you gather the necessary information to assess and treat a patient. Resting electrodes, alligator clips, rechargeable batteries, graph paper, cables and/or rolling carts are all accessories that can be put to good use in conjunction with top-of-the-line machines like the CardioCare 2000 or the CardioTouch 3000.
