What is the left ventricular function?
As a muscle pump composed of various chambers, the heart takes deoxygenated blood from the body and sends oxygenated blood to ensure the proper functioning of vital organs. One key chamber, the left chamber, is responsible for drawing oxygenated blood into the body and brain through the aort. The left ventricular function is the ability of the left ventricle to perform this work and can be disrupted in patients who have suffered heart failure or damage to infections or heart attack. Each of these hearts on the left side can be affected by heart failure and diagnostic tests can document the left ventricular function. Several of these tests are non -invasive and painless. The test uses sound -wave for the production of echocardiograms or moving images of the patient's beating heart. The test is ordered by a cardiologist and performed by a heart sonograph who presses the type of wand on the patient's chest when the machine collects data.
during an echo examinationThe cardiograph records the ejection fraction of the left ventricle (LVEF), which is recorded as a percentage. If this percentage falls below a certain point, it is considered to be a deteriorated function of the deteriorated left ventricle and other tests can be ordered. Healthy people who do not have a history of heart attacks have a Lvef of about 55 percent, which means that the left ventricle pumps more than half of the blood it holds every time it beats.
When a cardiologist finds a reduced LVEF and must understand more about the reduced function of the patient's left ventricle, he can order additional diagnostic tests. One is a string that measures how blood vessels and heart react with exertion. Many patients perform stress tests by walking on running pals or on stationary wheels while connected to a machine that monitors their heart function. Other patients lie on the tables and receive intravenous drugs designed to speed up the heart and imitate its activity during exercise.
Each type of stress test can detect and measure PR limit more clearlyBlood of the left ventricular heart muscle and to provide a clearer image of impaired left ventricular functions. If the cause of the left ventricular function is found, the cardiologist will treat the condition. Most forms of heart failure can be treated with a number of heart medicines.
