A normal heart beat generally consists of 2 distinct heart sounds, informally termed 'lub' and 'dub'. The first heart sound (lub) occurs at the beginning of the heart contraction (systole) and is the sound of the valves between the atria and ventricles closing. The second heart sound (dub) occurs at the end of the contraction, and is the sound of the valves between the major arteries and the ventricles closing.
What else can I help you with?
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 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 is lubb-dupp associated with?
heart sounds
What is lubb - dupp associated?
heart sounds
What is the best acouustic of heart?
Lupp and Dupp.
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 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.
What are important of lup and dup?
Lup and dup, or lupp and dupp, and sometimes also called lubb and dupp are the heart sounds. They are produced when the two different types of valves in the heart close, the atrioventriculars and the semilunars.
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"
Why is the lubb is louder than the dupp?
The lub is louder than the dupp because the closure of the atrioventricular valves (mitral and tricuspid) during systole generates more pressure and produces a louder sound than the closure of the semilunar valves (aortic and pulmonic) during diastole. This results in the lub sound being more prominent than the dupp sound during the cardiac cycle.
Is the 2nd heart sound in the period of isometric contraction?
no. it occurs at the beginning of isovolumetric relaxation.
When your heart goes bump bump is that one or to heart beats?
It really is lubb dupp and it is the sound of the 4 valves closing, two at a time. This occurs during one heart beat.
