Our hearts are truly a unique muscle. They can contract without neural stimulation, a property called “automaticity.” Automaticity is a product of special cardiac muscle cells called “pacemaker cells” because they set the pace of cardiac contractions. Pacemaker cells create contractions that last about 10 times as long as skeletal muscles.
