Cardiac pacing is a commonly used medical procedure to regulate the heart's rhythm. There are various synonyms for cardiac pacing that are used in the medical field, such as pacemaker implantation, cardiac resynchronization therapy, and artificial cardiac pacemaker. Pacemaker implantation is a surgical procedure that involves placing a small device in the chest that regulates the heartbeat. Cardiac resynchronization therapy is another type of pacing that uses two or more pacing leads to assist in synchronizing the heart's electrical signals. Artificial cardiac pacemakers are devices that deliver electrical impulses to the heart to regulate the heartbeat. Regardless of the terminology used, cardiac pacing remains an essential procedure for managing various heart rhythm disorders.
