Noun1.heart muscle - the muscle tissue of the heartheart muscle - the muscle tissue of the heart; adapted to continued rhythmic contraction
muscular tissue, muscle - animal tissue consisting predominantly of contractile cells
ticker, heart, pump - the hollow muscular organ located behind the sternum and between the lungs; its rhythmic contractions move the blood through the body; "he stood still, his heart thumping wildly"
cardiac pacemaker, SA node, sinoatrial node, pacemaker - a specialized bit of heart tissue that controls the heartbeat
papillary muscle - any of several muscles associated with the atrioventricular valves; "the papillary muscles contract during systole to prevent regurgitation of blood into the atria"
atrioventricular bundle, atrioventricular trunk, bundle of His, truncus atrioventricularis - a bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract
atrioventricular node - a node of specialized heart muscle located in the septal wall of the right atrium; receives impulses from the sinoatrial node and transmits them to atrioventricular bundle
myocardium - the middle muscular layer of the heart wall
Purkinje fiber - a specialized cardiac muscle fiber that is part of the Purkinje network
Purkinje network, Purkinje's system, Purkinje's tissue - a network of Purkinje fibers that carry the cardiac impulse from the atrioventricular node to the ventricles of the heart and causes them to contract
