Left ventricular function is typically assessed through diagnostic tests such as echocardiography, cardiac MRI, and nuclear imaging. Among these, echocardiography is the most commonly used due to its accessibility and non-invasive nature. Nurses should be familiar with the interpretation of ejection fraction (EF), which measures the percentage of blood pumped out of the left ventricle with each heartbeat. An EF of 55-70% is considered normal; values below this range may indicate heart failure or other cardiac conditions.
