Tiếng tim T1 và T2: Cấu trúc, chức năng và ý nghĩa lâm sàng
The human heart, a tireless pump, orchestrates the continuous flow of blood throughout the body. This rhythmic symphony of life is punctuated by a series of sounds, the most prominent being the S1 and S2 heart sounds. These sounds, often described as "lub" and "dub," respectively, provide a fundamental window into the heart's mechanical function.
The S1 and S2 heart sounds are fundamental components of the cardiac cycle, reflecting the intricate interplay of valves, chambers, and blood flow. Understanding the origins, characteristics, and clinical significance of these sounds is paramount for healthcare professionals in evaluating cardiovascular health and diagnosing potential abnormalities. By carefully listening to the heart's rhythmic dialogue, we gain valuable insights into its well-being and the overall health of an individual.
