If you have Addison's disease, your adrenal glands don't make enough hormones. Unlike adrenal fatigue, this is an illness that doctors can test and recognize. In most cases of this disease, the adrenal glands have been damaged by the immune system. Other causes of Addison's disease include: Tuberculosis (TB)
Cardiac monitoring generally refers to continuous monitoring of heart activity, generally by electrocardiography, with assessment of the patient's condition relative to their cardiac rhythm. It is different from hemodynamic monitoring, which monitors the pressure and flow of blood within the cardiovascular system. The two may be performed simultaneously on critical heart patients. A small monitor worn by an ambulatory patient (one well enough to walk around) is known as a Holter monitor. Transmitting data from a monitor to a distant monitoring station is known as telemetry or biotelemetry. 1 Emergency medical services.
1 Echocardiogram (EKG or ECG): Also known as a cardiac echo, this test uses sound waves to take pictures of your heart.  Holter monitor: This monitor is worn for at least 24 hours while you go about your normal activities. It allows your doctor to track changes in your heartâs rhythm throughout the day.
