Noun1.cardiac muscle - the muscle tissue of the heartcardiac 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

Potential repair by cell grafting or mobilizing endogenous cells holds particular attraction in heart disease, where the meager capacity for cardiomyocyte proliferation likely contributes to the irreversibility of heart failure.
Pathomechanistically, a variety of diverse stress signals on the cardiomyocyte trigger loss of myofibrils and cardiomyocyte death, thereby activating a vicious cycle of cardiac stress and deterioration during terminal heart failure.
Further investigation showed that the difference between a day and a week was in the amount of ERBB2 on the cardiomyocyte membranes.
The sections include the structural and molecular bases of ion channel function, intermolecular interactions and cardiomyocyte electrical function, models of cardiac excitation, arrhythmia mechanisms, diagnostic evaluation, ventricular and supraventricular tachyarrhythmias, arrhythmias in special populations, electrical therapy, and new approaches.
In previous work, published in Science, Martin's team identified a signaling pathway responsible for cardiomyocyte proliferation during development.
In mice, fish, and avian embryos, the heart is a TCDD target during fetal development, which results in reduced cardiomyocyte proliferation, altered fetal heart size, and disruptions in neovascularization (Ivnitski-Steele and Walker 2005).
Kuhn points out that research in the 1930s and 1940s suggested that cardiomyocyte division may continue after birth, and recent reports about myocardial regeneration in zebrafish and neonatal mice suggest that some young animals regenerate heart muscle by using mechanisms of muscle cell division.
The mechanical integrity of the nanotube scaffold was also stronger, allowing it to withstand repeated cardiomyocyte contractions, whereas the gel lacking nanotubes ruptured quickly.
About the xCELLigence System RTCA Cardio Instrument The latest member of the xCELLigence product family, the RTCA Cardio Instrument is a 96-well cell analyzer for the dynamic monitoring of cardiomyocyte beating and cellular events by impedance readings.
While syndecan-2 expression in cardiac non-myocytes is in apparent contrast to the strict cardiomyocyte expression observed in the current study, a direct comparison of data obtained from an immunohistochemical analysis of early stage chick cardiac tissue (day 3-5) with molecular analysis of later stage rat cardiac mRNA is difficult due to the species difference and the tremendous morphogenetic activity that occurs between early and late stages of embryogenesis.
The red wine antioxidant resveratrol prevents cardiomyocyte injury following ischemia-reperfusion via multiple sites and mechanisms.
Our success with Thermo Fisher Scientific's workflow reagents, in particular their reagents for the generation of cardiomyocytes from pluripotent stem cells, has enabled us to develop a broad panel of patient-derived cardiomyocyte models to study inherited heart disease.
