Definition that contains heart muscle
- mi destruction of heart tissue resulting from obstruction of the blood supply to the heart muscle
- cardiomyopathy a disorder (usually of unknown origin) of the heart muscle (myocardium)
- defibrillation treatment by stopping fibrillation of heart muscles (usually by electric shock delivered by a defibrillator)
- truncus atrioventricularis a bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract
- cardiac cycle the complete cycle of events in the heart from the beginning of one heart beat to the beginning of the next; an electrical impulse conducted through the heart muscle that constricts the atria which is followed by constriction of the ventricles
- myocardial infarction destruction of heart tissue resulting from obstruction of the blood supply to the heart muscle
- coronary insufficiency inadequate blood flow to the heart muscles; can cause angina pectoris
- 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
- ventricular fibrillation fibrillation of heart muscles resulting in interference with rhythmic contractions of the ventricles and possibly leading to cardiac arrest
- cardiac insufficiency inadequate blood flow to the heart muscles; can cause angina pectoris
