What muscle helps the heart contract?
Cardiac muscle tissue works to keep your heart pumping through involuntary movements. This is one feature that differentiates it from skeletal muscle tissue, which you can control. It does this through specialized cells called pacemaker cells. These control the contractions of your heart.
What causes cardiac muscle contract?
Contraction in cardiac muscle occurs due to the the binding of the myosin head to adenosine triphosphate ( ATP ), which then pulls the actin filaments to the center of the sarcomere, the mechanical force of contraction.

What is it when your heart is only functioning at 10%?
A normal heart pumps blood out of its left ventricle at about 50 to 70 percent — a measurement called an ejection fraction, according to the American Heart Association. “Don was at 10 percent, which is basically a nonfunctional heart,” Dow said. “When a heart is pumping at only 10 percent, a person can die very easily.
