Cardiac function refers to the ability of the heart to pump blood effectively throughout the body. This process involves the coordinated contraction and relaxation of the heart's chambers, which include the atria and ventricles. The heart's electrical system regulates these contractions, ensuring that blood is delivered to vital organs and tissues. Several factors influence cardiac function, including heart rate, blood pressure, and the strength of the heart's contractions. Conditions such as heart disease or hypertension can impair cardiac function, leading to reduced blood flow and oxygen delivery. Maintaining a healthy lifestyle can support optimal cardiac function and overall heart health.
