What causes the sounds that are normally heard when listening to the heart through a stethoscope?
The sound is caused by the closing of valves in the heart.
What makes the first sound of a heartbeat?
The first sound of a heartbeat is caused by the closing of the atrioventricular valves (mitral and tricuspid valves) in the heart and marks the beginning of ventricular systole, where the ventricles contract to pump blood. This sound is known as the "lub" sound of the heartbeat.
What heart sound is stronger at the apex of the heart?
First heart sound S1-LUB
Which part of the heart makes the heartbeat sound?
A heartbeat produces the familiar "LUB-DUP" sounds as the chambers contract and the valves close. The first heart sound, "lub," is heard when the ventricles contract and the atrioventricular valves close. This sound last longest and has a lower pitch. The second heart sound, "dub," is heard when the relaxation of the ventricles allows the semilunar valves to close.
What is the Lub-Dub sound?
In the lub-dub version of heart sound, dub is caused by the back rush of blood against a closed aortic or pulmonary valve.
What's sound of the heart?
Most people can hear two heart sounds per cycle - a quiet "lub" and a louder "dub". The "lub" sound is the contraction of the two atria, which results in the ventricles being filled with blood. The "dub" sound is the contraction of the two ventricles, which results in blood being forced into the arterial system. However, a trained physician can hear four sounds - the two described above, and two more that represent the sound of the valves opening back up after the contraction is over.
What is an endocardiogram?
This is a procedure that checks the status of the heart chambers and valves. Sound waves are used to produce images of the heart and check for any problem in heart muscles or valves. This exam is usually suggested if a doctor believes that the patients blood is being pumped abnormally.
Where is the s1 heart sound heard the loudest?
S1 makes a "lub" sound. It is the first heart sound in a normal rhythm. The sound is produced when the AV valves close.
When your heart pounds what is making the sound come from your heart?
The sound coming from your heart is the sound of the valves in the heart closing and the turbulence in the blood that results. In a normal healthy adult the first sound (or lub) is from the closing of the AV valve and the second sound (or dub) is from the closing of the semilunar valve.
