Kardiotöö

Kardiotöö, also known as cardiac work, refers to the mechanical activity of the heart, specifically the amount of work the heart does to pump blood throughout the body. It is a crucial indicator of the heart's efficiency and health. The work done by the heart is directly related to the heart's output, which is the product of its stroke volume and heart rate. Stroke volume is the amount of blood pumped by the heart with each contraction, while heart rate is the number of contractions per minute.

Cardiac work is influenced by several factors, including the heart's size, the force of its contractions, and the resistance it faces. A healthy heart maintains an optimal balance between these factors to ensure efficient blood circulation. Increased cardiac work can occur due to various conditions, such as hypertension, heart failure, or physical exertion. Conversely, decreased cardiac work may indicate a weakened heart or other cardiovascular issues.

Monitoring cardiac work is essential for diagnosing and managing heart diseases. Techniques such as echocardiography, cardiac catheterization, and stress testing are commonly used to assess the heart's performance. Early detection and management of abnormal cardiac work can significantly improve patient outcomes and quality of life.

In summary, kardiotöö is a critical measure of the heart's function, reflecting the work it does to pump blood. Understanding and monitoring cardiac work are vital for maintaining heart health and managing cardiovascular conditions.
