How is a heart beat produced?

The heart beat, also called heart sounds, is produced by the closing of the valves. The valves produce two sounds, known as lub-dub. The atrioventricular valve closing produces the first sound, or lub, and the semilunar valve closing produces the second sound, or dub.


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.


The lubb-dupp heart sounds are made by the?

The "lubb" sound is produced by the closing of the Atrioventricular (Bicuspid and Triscuspid) valves , while the "dupp" sound is produced by the closing of the Semilunar (Aortic and Pulmonary) valves.


What produces the systolic korotkoff sound?

The first Korotkoff sound is the sound produced by the turbulence of the AV (atrioventricular valves) closing specifically the tricuspid and mitral valves. The second Korotkoff sound is produced by the closure of the aortic and pulmonary valves. You can hear a splitting of the second heart sound in a highly efficient heart.


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 first heart sound lub is caused by what?

The first heart sound "lub" is caused by the closing of the mitral and tricuspid valves during the beginning of systole (ventricular contraction). The closure of these valves creates vibrations in the surrounding fluid and tissues, resulting in the characteristic sound.


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.


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.


The first heart sound is heard when?

S1 which is the closing of the atrioventricular valves.


What sounds does a 'healthy heart' make?

slow


What does the beating sound of your heart come from?

The sound of a heart beat is caused by the closing of the valves in the heart.


What cause the lubb-dupp heart sounds that are heard while talking an apical pulse?

The closing of the valves in the heart. The first sound is caused by the closing of the atrioventricular valves within the heart. The second sound is caused by the shutting of the aortic and pulmonary valves.
