The cardiac device is intended for use by patients who either have, or are at risk of having cardiac disease and those that demonstrate intermittent symptoms indicated by cardiac disease and require cardiac monitoring on a continuing basis. The device continuously records ECG data and, upon detection by an ECG analysis algorithm or manually initiated by the patient, automatically delivers the recorded cardiac activity to the server where it is presented and can be reviewed by a medical professional. The data received from the cardiac device can be used for arrhythmia analysis, reporting, and signal measurements. The cardiac device is not intended to sound any alarms. This cardiac device does not deliver any therapy, administer any drugs, provide interpretive or diagnostic statements, or provide any life-support. This cardiac device is for prescription use only.
