The Zio Patch is a small adhesive patch placed on the skin over the left chest. It is wireless and allows for 24 hour continuous cardiac monitoring. The use of this device is increasing as it offers a more comfortable alternative to the Holter monitor for patients. The ECG leads seen on this x-ray are from the patient's admission and not part of the Zio Patch.
