Abstract

A wearable monitoring device includes a plurality of cardiac sensing electrodes, a monitor, at least one motion sensor, and a controller. The plurality of cardiac sensing electrodes are positioned outside a body of a subject and to detect cardiac information of the subject. The monitor administers a predetermined test to the subject, and has a user interface configured to receive quality of life information from the subject. The at least one motion sensor is positioned outside the body of the subject and to detect subject motion during the predetermined test. The controller is communicatively coupled to the plurality of cardiac sensing electrodes, the monitor, and the at least one motion sensor, and receives and stores the detected cardiac information, the quality of life information, and the detected subject motion. The controller further communicates the stored detected subject motion and the quality of life information to a remote computer.

Claims
