| | Heart - Wikipedia, the free encyclopedia |
 | | The term cardiac means "related to the heart", from the Greek kardia (καρδια) for "heart". | | | This is in contrast with skeletal muscle, which requires either conscious or reflex nervous stimuli. | | | Finally complete cardiac diastole involves relaxation of the atria and ventricles in preparation for refilling with circulating blood. |

| | Cardiac nuclear medicine tests are indicated for individuals with unexplained chest pain or chest pain brought on by exercise (called angina) to permit the early detection of heart disease. | | | Cardiac nuclear medicine refers to these diagnostic tests that are used to examine the anatomy and function of the heart. | | | Cardiac nuclear medicine procedures have been done for more than three decades, and no long-term adverse effects have been reported from such low-dose studies. |

| | Heart Physiology |
| | The relaxation of the cardiac muscle tissue in the ventricles is called diastole. | | | Approximately the size of a clenched fist, the heart is composed of cardiac muscle tissue that is very strong and able to contract and relax rhythmically throughout a person's lifetime. | | | When the ventricles relax, they make room to accept the blood from the atria. |

| | Clinical and in vitro studies show different dynamic behavior under different physiological conditions, such as aortic versus mitral position, and the expected flow patterns and leaflet movement can be predicted by the FSI results. | | | The interaction between blood and the structures that transport it plays an important role in many biofluid dynamic flow problems, such as blood flow in the heart and vessels, through heart valves, in cardiac assist devices, and in artificial organ design. | | | Different numerical techniques have been used to tackle this fluid-structure interaction (FSI) problem. |

| | The period of ventricular relaxation is known as diastole! | | | The Cardiac Cycle: The cardiac cycle includes all events that take place within the heart, from the beginning of one systolic contraction of the ventricles to the onset of the next systolic contraction of the ventricles; that is, by convention, the starting point of the cardiac cycle is the beginning of systole! | | | The increased stretch of the ventricles causes them to contract more forcefully; that is, the stretch of the ventricles has a positive inotropic effect. |

| | Their endings terminate upon ordinary cardiac muscle within the ventricles, and the impulse proceeds through the ventricular muscle at about 0.3 to 0.5 meters per second. | | | Next, as the ventricles begin to relax, the aortic and pulmonic semilunar valves close, the AV valves open, and blood flows into the ventricles to begin another cycle. | | | The sinoatrial (SA) node is a small mass of specialised cardiac muscle situated in the superior aspect of the right atrium. |
