Yes. : Yes. A pacemaker is placed in the heart to prevent the heart from beating too slow. As an example a pacemaker may be set to ensure the heart beats 70 times a minute. If your intrinsic heart beats slower than 70, or if your heart stops beating (as in a cardiac arrest), then the pacemaker will send an electrical impulse to the heart to keep beating at 70 beats per minute. To avoid brain damage, the person must also be breathing normally. If the person is not breathing normally (10-20 breaths per minute), call 911 and initate cpr.
