Note that the right ventricular lead in this case has two thickened aspects that represent conduction coils and that the generator is larger than typical pacemaker generators, demonstrating that this device is both a pacemaker and a cardioverter-defibrillator, capable of delivering electrical shocks for dangerously fast abnormal ventricular rhythms.

A cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural pacemaker of the heart) is a medical device that generates electrical impulses delivered by electrodes to cause the heart muscle chambers (the upper, or atria and/or the lower, or ventricles) to contract and therefore pump blood. By doing so, this device replaces and/or regulates the function of the electrical conduction system of the heart.

National Pacemaker Awards

The National Pacemaker Awards are awards for excellence in American student journalism, given annually since 1927. The awards are generally considered to be the highest national honors in their field, and are unofficially known as the "Pulitzer Prizes of student journalism".

The National Scholastic Press Association administers the contest for high school programs, while the Associated Collegiate Press administers the college and university contests. Pacemakers are awarded annually at the JEA/NSPA National Conference (for high schools) and the ACP/CMA National College Media Convention (for colleges) in the following categories: Newspaper, Online, Yearbook/Magazine, and Broadcast.
