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.
The fact of the matter is that an ECG and an EKG are the exact same thing. Thatâs right, the most surprising difference between an ECG and an EKG is that there is no difference at all. B oth ECG and EKG stand for electrocardiogram. So, if an ECG is the same thing as an EKG, then why are there two different abbreviations?
