Although not part of the original plan, the Joint Chiefs of Staff also created specified commands that had broad and continuing missions but were composed of forces from only one service.

Longer the test higher will be the sustainability and stronger will be the heart. An estimated time calculated to know how long a stress tests take is around 30 minutes without stoppage. This is considered as a normal time of a stress test if a person is strong enough to sustain the external stress and regular exercise.
Your heart will be stressed, either through exercise or through the use of medication. During the test you will be constantly monitored by a Nurse Practitioner or a Physician. The actual stress portion of the test takes about 10 to 15 minutes, however the preparation takes longer (up to 30 minutes). Before the end of the stress test, a second injection (Cardiolite) will be administered.
