Is S1 Systole Or Diastole Official

The S1 heart sound is an essential component of the cardiac physical examination. Changes in the S1 sound can indicate various cardiac conditions, such as:

To answer the question definitively, we have to look at the two phases of the heartbeat: is s1 systole or diastole

Clinically, distinguishing S1 as a systolic sound has profound diagnostic importance. For example, auscultating a murmur—an abnormal whooshing sound caused by turbulent blood flow—depends entirely on its timing relative to S1 and S2. A murmur that occurs between S1 and S2 is a (e.g., in mitral regurgitation or aortic stenosis). A murmur that occurs after S2 but before the next S1 is a diastolic murmur (e.g., in mitral stenosis or aortic regurgitation). Identifying S1 as the starting gun of systole allows a physician to instantly classify a murmur and narrow down a list of potential valve pathologies. Furthermore, the intensity of S1 itself provides clues: a loud S1 can indicate a narrow mitral valve opening (mitral stenosis) or a short PR interval (rapid filling), while a soft S1 may suggest a poorly contracting ventricle or prolonged PR interval. These assessments are only meaningful if the clinician correctly identifies S1 as the systolic anchor. The S1 heart sound is an essential component

If you are feeling your pulse at your wrist (radial pulse) or neck (carotid pulse), the beat you feel is almost perfectly synchronized with S1 . This is because S1 is the sound of the heart preparing to eject the blood that creates the pulse wave. Why Timing Matters A murmur that occurs between S1 and S2 is a (e
