At least one aspect is directed to a wearable treatment device that includes a cardiac sensing electrode, a treatment electrode, a user interface, and a sensor. The cardiac sensing electrode detects cardiac information, and the treatment electrode applies treatment to the subject. The user interface receives quality of life information from the subject, and the sensor detects subject activity and wellness information. A controller coupled with the cardiac sensing electrode, the treatment electrode, the user interface, and the sensor receives the detected cardiac information, the quality of life information, and the detected subject activity and wellness information, and determines that treatment is to be applied to the body of the subject based upon the detected cardiac information. The controller can also adjust the treatment based on at least one of the detected subject activity and wellness information and the quality of life information, and an alarm module provides an alarm after the cardiac information is detected and before the treatment is applied to the body of the subject.
