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).
Electrocardiogram (EKG) An EKG is a noninvasive diagnostic exam performed to detect electrical activity in the heart. It is commonly performed after patients have experienced heart attack symptoms including chest pain, shortness of breath and heart palpitations, or as part of a routine heart disease screening.
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.
