Cardiac muscle resists fatigue so well because it's got more mitochondria than skeletal muscle. With so many power plants at its disposal, the heart doesn't need to stop and chill out. It also has a steady supply of blood bringing it oxygen and nutrients.

Explanation:
Because the myofibrils are also attached to the intercalated discs, the cells "pull together" quite efficiently. ... The properties of cardiac muscle cell membranes differ from those of skeletal muscle fibres. As a result, cardiac muscle tissue cannot undergo tetanus (sustained contraction).
