English: This image shows two different kinds of devices used for the remote monitoring of pacemaker patients. The one on the left, the gray device, is the more advanced device that actually communicates with the pacemaker through the peripherial that is placed over the pacemaker in the patient's chest. The device on the right is an older version of remote monitoring device. It requires the use of a telephone handset and the patient must put the bracelets on each wrist allowing the device to monitor heartbeat. The white round object is a high powered magnet that is used to trigger the pacemaker into beginning to pace allowing the person who is conducting the remote monitoring to determine if the pacemaker is still functioning correctly.
