südamevolüüm

Südamevolüüm refers to the volume of blood pumped by the heart per unit of time, typically measured in liters per minute. It is a key indicator of cardiac function and overall cardiovascular health. This volume is determined by two main factors: heart rate, which is the number of times the heart beats per minute, and stroke volume, which is the amount of blood ejected from the left ventricle with each beat. Südamevolüüm can be influenced by various physiological and pathological conditions.

During exercise, the body's demand for oxygen increases, leading to a rise in südamevolüüm. This is achieved through an increase in both heart rate and stroke volume, allowing the heart to efficiently deliver oxygenated blood to the working muscles. In contrast, certain medical conditions, such as heart failure, can impair the heart's ability to pump blood effectively, resulting in a reduced südamevolüüm. This can lead to symptoms like fatigue, shortness of breath, and swelling.

Healthcare professionals often measure südamevolüüm as part of diagnostic assessments to evaluate heart function and monitor the effectiveness of treatments. Various non-invasive and invasive methods exist for its determination, including echocardiography and cardiac catheterization. Understanding and monitoring südamevolüüm is crucial for managing cardiovascular diseases and maintaining a healthy circulatory system.
