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 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.
The heart sounds are due to?
The sounds in the heart are caused by the opening and closing of the ventricles. There are two sounds and they are called by the first heart sound (S1) and second heart sound (S2), produced by the closing of the AtrioVentricular valves and semilunar valves respectively.
When was No Sound But a Heart created?
No Sound But a Heart was created in 1987.
Is the lubb sound s1 or s2?
s1. It is due to the closure of the AV valves at the start of systole
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).
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.
What does the lub-dub sound represent?
The first heart sound or "lub" results from closure of the tricuspid and mitral valves. It is a rather low-pitched and a relatively long sound which, as indicated in, represents the beginning of ventricular systole. The second heart sound, or "dub," marks the beginning of ventricular diastole. It is produced by closure of the aortic and pulmonary (pulmonic) semilunar vanes when the intraventricular pressure begins to fall
What part of the heart beat makes the heart beat sound?
The closure of the Mitral and tricuspid valves causes us to hear the first heart sound or S1 (M1T1) while the closure of the aortic and pulmonary valves allows us to hear the second heart sound or S2 (A2P2).
What is the religious aspect of water?
water signify's sound doctrine
What creates the S2 sound?
Go oilers goGolf leafs golf
What produces the heart sounds as heard with a stethocope?
The closing of the mitral and tricuspid valves produces the S1 sound, followed by the closing of the aortic and pulmonic valves, which produce the S2 sound. In sequence, it sounds like "lub-DUB, lub-DUB, lub-DUB".
