What should I do if the ambulatory ECG monitoring device becomes loose or stops recording while I am wearing it?

First follow the troubleshooting instructions provided when you received the device, and contact the department responsible for the monitoring. Note the time you noticed the problem, any device messages, and whether you had any symptoms at that time. Tell them honestly which periods may not have been recorded. Do not try to repair the device yourself or fabricate monitoring data. Whether to continue wearing it or repeat the monitoring should be confirmed by the responsible staff. If you develop symptoms that need urgent attention, do not wait for the device to recover before seeking help.
