Valves opening and closing and blood flowing
The normal action of the heart, the pumping of the chambers and the closing of the valves.
Closing of the valves
Lub = closing the AV valves
Dub = closing of the semi lunar valves
The heart beats when the blood pumps
At the beginning of ventricular systole first heart sound (lubb) originates due to the closure of atrioventricular valves .
The second heart sound (dupp) originates due to the closure of the semi-lunar valves during diastole of ventricle.

Is audible s3 heart sounds normal?
Such questions will continue to come from senior doctors. When you listen some abnormal heart sounds, you should go for ecocardiogram of the patient. With Doppler study, you will get complete information of the defects and blood flow of the heart. You have to listen heart sounds very routinely to know the 'normal' heart sounds. There is no short cut for the same.
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 causes the lub-dup heart sounds that are heard with the stethoscope?
The cardiac sounds (typically described as lub-dub) are caused by the closing of the cardiac valves. The first sound (lub) is caused by the closing of the mitral and tricuspid valves and the second (dub) is caused by the closing of the aortic and pulmonic valves.
What causes the lubb dupp heart sounds that are heard while taking a apical pulse?
The closure of mitral and tricuspid valves causes the first heart sound. The second heart sound is produced by the closure of semilunar valves (pulmonic and aortic valves).
What causes heart sounds?
Heart sounds are created primarily from turbulence in blood flow created by the closures of the valves.
What are the sources and clinical significance of the heart sounds?
The normal heart sounds are described as a lubb dubb. These sounds are due to the closing of the valves. If a murmur is heard, the valves are not closing properly and there is a back flow of blood. Also if the normal heart sounds are not in a rhythm, there is something wrong with the way the heart is working.
In relation to the normal heart sounds when would you expect to hear the abnormal sounds?
Abnormal sounds may be heard before, after, or during the normal heart sounds. For instance, sounds associated with stenosis may be heard before the closing of that valve.
What are heart murmurs and what is their clinical significance?
A heart murmurs is an abnormal sound consisting of a clicking, rushing, or gurgling noise that either is heard before, between , or after the normal sounds, or may may mask the normal heart sounds.
What causes the heart sounds normally heard in a healthy individual?
Normal heart sounds are caused by the heart beating. This is the process of the heart muscle contracting and relaxing as blood flows through the various chambers.
What is medical term for sound heard during heart beat?
In medical terminology, the normal "lub dub" sounds of a heartbeat are labeled S1 and S2. Abnormal sounds that may be heard include S3, S4, rub, murmur, and snap.
What causes the sounds heard through a stethoscope?
Your heart beat of course.
What produce the heart sounds heard with a stethoscope?
The valves opening and closing
Heart sounds are most easily heard by placing a stethoscope?

The monosyllables describing heart sounds during the cardiac cycles are what?
Lubb dubb corresponds to the heart sounds heard during systole and diastole, respectively.
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.
When do you hear the heart beat?
Actually , the heart beat is heard when the heart valves closes ! The sounds are described as "lupp-dupp"
