The potential benefits of a pacemaker include normalized heart rhythm and improved quality of life. Physicians recommend pacemakers for patients in varying degrees of cardiac distress, so the potential benefits of a pacemaker will vary, as well.

If an abnormal heartbeat has begun to interfere with your daily activities, your doctor may recommend a pacemaker. Pacemakers are generally inserted in people with very slow heart rates or with a condition known as heart block.

Pacemaker warning signs can alert a pacemaker patient to the potential complications or failure of his cardiac device. Pacemakers are small electronic mechanisms that surgeons implant into the upper chest of some cardiac patients.

If you've had a pacemaker implanted, you may be hesitant or cautious about resuming an exercise routine. You may be concerned about the pacemaker's ability to achieve or maintain an accelerated heart rate, your limitations in terms of strength, or the durability of the pacemaker.
