It depends on where you saw it, some people use S2 as a symbol for a heart, like <3. But S2 can also stand for:

S2 (also known as S0-2) is a star that is located close to the radio source Sagittarius A*

The S2 is a regional railway line of the S-Bahn Zürich on the Zürcher Verkehrsverbund (ZVV), Zürich transportation network, and is one of the network's lines connecting the cantons of Zürich and Schwyz respectively Glarus and Gallen.

S2 is a line on the Berlin S-Bahn.

S2 (Style System 2) is an object-oriented programming language developed in the late 1990s by Brad Fitzpatrick, Martin "Mart" Atkins, and others for the online journalling service LiveJournal in order to allow users full control over the appearance of their pages.

Asparagusic acid, S2(CH2)2CHCO2H is an organosulfur carboxylic acid present in the vegetable asparagus and may be the metabolic precursor to other odorous thiol compounds. Biosynthetic studies revealed that asparagusic acid is derived from isobutyric acid.

S2 Records, formerly named Sony Soho Square after its location at London's Soho Square, is a record label subsidiary of Sony Music. It is headed by Muff Winwood, brother of Steve Winwood.

S-2 - S-2 was the designation of a Stalinets class submarine of the Soviet Navy. In early 1940, it entered Swedish territorial waters in the Sea of Åland. There it hit a Swedish naval mine, and sank on January 2, 1940. All of the 50 crewmembers on board perished.

Which heart sound results from the AV valves closing?

S2, also called the second heart sound, or "dub" when characterized by the sound lub-dub.


What is s1s2?

S1 S2 are heart sounds. The S1 sound occurs at the beginning of systole (end of diastole). The S2 sound occurs at the beginning of Diastole (end of systole).


Why does the second heart sound occur after the T wave?

The second heart sound (S2) occurs after the T wave because it corresponds to the closure of the aortic and pulmonic valves in the heart. The T wave represents ventricular repolarization, which happens after ventricular contraction and ejection of blood through the aortic and pulmonic valves. The closure of these valves generates the S2 sound.


What does a healthy heart sound?

In healthy adults, there are two normal heart sounds often described as a lub and a dub, that occur in sequence with each heart beat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the AV valves and semilunar valves respectively.


The second heart sound occurs as a result of valve closure due to?

The second heart sound, also called S2, is a result of the closing of the aortic and pulmonic valves. The heart sounds are described as sounding like "lub-dub".


What sounds does a 'healthy heart' make?

slow


What is the sound of second heart sound?

The second heart sound (S2) is a short burst of auditory vibrations of varying intensity, frequency, quality, and duration. It has two audible components, the aortic closure sound (A2) and the pulmonic closure sound (P2), which are normally split on inspiration and virtually single on expiration. S2 is produced in part by hemodynamic events immediately following closure of the aortic and pulmonic valves. The vibrations of the second heart sound occur at the end of ventricular contraction and identify the onset of ventricular diastole and the end of mechanical systole.


What does the word lub-dupp mean?

It refers to the sound the heart makes, heard through the stethescope. lub (S1) is made when the atrioventricular valves in the heart close. dupp (S2) is made when the semilunar valves in the heart close.


Which conditions increase the intensity of S2?

Conditions that can increase the intensity of the S2 heart sound include high blood pressure, pulmonic stenosis, aortic stenosis, and conditions that lead to increased blood flow through the pulmonary or aortic valves.


What is the origin of heart sounds?

Heart sounds originate from the closure of heart valves during the cardiac cycle. The first heart sound (S1) is produced by the closure of the mitral and tricuspid valves, while the second heart sound (S2) is caused by the closure of the aortic and pulmonary valves. These sounds can be heard using a stethoscope during a physical examination.


Why S1 is the loudest sound?

S1, or the first heart sound, is the loudest because it is produced by the closing of the atrioventricular valves (mitral and tricuspid valves) during systole. This closure creates a more forceful and prominent sound compared to the closing of the semilunar valves which produce S2.


How do heart sounds correlate with ecg readings?

Heart sounds, specifically the &quot;lub&quot; (S1) and &quot;dub&quot; (S2), correlate with specific phases of the cardiac cycle as reflected in ECG readings. The S1 sound occurs with the closure of the atrioventricular valves, coinciding with the QRS complex, which represents ventricular depolarization. The S2 sound occurs with the closure of the semilunar valves, aligning with the end of the T wave, which represents ventricular repolarization. Thus, heart sounds provide auditory confirmation of the mechanical events depicted in the ECG.
