Two different types of muscle. Your heart is Cardiac Muscle. They don't tire. The muscles in your arms. legs etc is Striated/Skeletal Muscle. They do tire.

There are different types of muscle cells in the body. Cardiac muscle cells have a different structure. They do not fatigue in the sense that skeletal or smooth muscles fatigue. They do rest between contractions.
