These statistics are presented only in the hope that they may be interesting to some people. The word 'prevalence' of Insomnia usually means the estimated population of people who are managing Insomnia at any given time (i.e. people with Insomnia). The term 'incidence' of Insomnia means the annual diagnosis rate, or the number of new cases of Insomnia diagnosed each year (i.e. getting Insomnia).
Exercise Stress Test. A stress test, sometimes called a treadmill test or exercise test, helps a doctor find out how well your heart handles work. As your body works harder during the test, it requires more oxygen, so the heart must pump more blood. The test can show if the blood supply is reduced in the arteries that supply the heart.
For the stress test you will have EKG leads placed on your chest and you will be monitored closely. You may walk on a treadmill, ride a bike or receive a medicine. All these will increase your heart rate to stress your heart. Once your heart rate is increased, images of your heart will be taken.
