pacemaker
Significado: A small electronic device implanted in the chest to regulate an abnormal heart rhythm by sending electrical impulses to the heart muscle.
A pacemaker monitors the heart's rhythm and delivers electrical pulses only when the heartbeat is too slow or irregular. The term is also used in athletics to describe a runner who sets the pace for others in a race. In biology, the sinoatrial node is the heart's natural pacemaker. Collocations include 'fitted with a pacemaker,' 'pacemaker battery,' and 'pacemaker check.'
