An artificial heart pacemaker is a small battery-operated device that helps the
heart beat at the correct rate. It sends electrical impulses to the heart through
a wire(s), replacing the function of your natural pacemaker.
With just a push of a button, Life Alert can get you the medical attention that
you need. In case of an emergency, Life Alert will notify the paramedics of all
your medical conditions so they will be better prepared.
In the beginning pacemakers sent one steady beat to the heart through a single electrode.
Pacemakers of today can sense when a heart needs help and delivers just the right
amount and interval of impulse.
