Because the measurements of ejection fraction are done at rest, they often give little useful information about how limited a person may be with exercise. (Sometimes, we can do exercise MUGAs or exercise echocardiograms to get this information. )Also, since the heart must pump blood through an extensive network of blood vessels to get it to the muscles to do the work of walking, lifting, and so on, it is important to test how the heart, lungs, blood vessels, and muscles all work together during exercise to really determine how patients use what they have in terms of heart function.
Heart Problems Certain heart muscle cells have the ability to contract spontaneously, and these cells generate electrical signals that spread to the rest of the heart and cause it to contract with a regular, steady beat. We need to face this challenge at all levels in order to convert our failures into successes. Stroke volume, in turn, depends on several factors: the rate at which blood returns to the heart through the veins; how vigorously the heart contracts; and the pressure of blood in the arteries, which affects how hard the heart must work to propel blood into them. A last resort in the treatment of heart failure is heart transplantation, in which a patients diseased heart is replaced with a healthy heart from a person who has died of other causes. Failure of the right ventricle produces systemic edema, reflecting hepatic and visceral engorgement. |
