In addition to these normal sounds, a variety of other sounds may be present including heart murmursadventitious soundsand gallop rhythms S 3 and S 4. Heart murmurs are generated by turbulent flow of blood and a murmur to be MP3) as turbulent flow must require pressure difference of at least 30 mm of hg between the chambers and the pressure dominant chamber will Dubbing - Various - The Sound Of Nature 2 (File flow the blood to non dominant chamber in diseased condition which leads to Left-to-right shunt or Right-to-left shunt based on the pressure dominance.
Turbulence may occur inside or outside the heart; if it occurs outside the heart then the turbulence is called Bruit. Murmurs may be physiological benign or pathological abnormal. Abnormal murmurs can be causes by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it. Abnormal murmurs may also occur with valvular insufficiency regurgitationwhich allows backflow of blood when the incompetent valve closes with only partial effectiveness.
Different murmurs are audible in different parts of the cardiac cycledepending on the cause of the murmur. The first heart sound, or S 1forms the "lub" of "lub-dub" and is composed of components M 1 mitral valve closure and T 1 tricuspid valve closure. Normally M 1 precedes T 1 slightly. It is caused by the closure of the atrioventricular valvesi.
When the ventricles begin to contract, so do the papillary muscles in each ventricle. The papillary muscles are attached to the cusps or leaflets of the tricuspid and mitral valves via chordae tendineae heart strings. When the papillary muscles contract, the chordae tendineae become tense and thereby prevent the backflow of blood into the lower pressure environment of the atria.
The chordae tendineae act a bit like the strings on a parachute, and allow the leaflets of the valve to balloon up into the atria slightly, but not so much as to evert the cusp edges and allow back flow of blood. It is the pressure created from ventricular contraction that closes the valve, not the papillary muscles themselves.
The contraction of the ventricle begins just prior to AV valves closing and prior to the semilunar valves opening. The sudden tensing of the chordae tendineae and the squeezing of the ventricles against closed semilunar valves, sends blood rushing back toward the atria, and the parachute-like valves catch the rush of blood in their leaflets causing the valve to snap shut. The S1 sound results from reverberation within the blood associated with the sudden block of flow reversal by the valves.
The delay of T1 even more than normally causes the split S1 which is heard in a right bundle branch block. The second heart sound, or S 2forms the "dub" of "lub-dub" and is composed of components A 2 aortic valve closure and P 2 pulmonary valve closure. Normally A 2 precedes P 2 especially during inspiration where a split of S 2 can be heard. It is caused by the closure of the semilunar valves the aortic valve and pulmonary valve at the end of ventricular systole and the beginning of ventricular diastole.
As the left ventricle empties, its pressure falls below the pressure in the aorta. Aortic blood flow quickly reverses back toward the left ventricle, catching the pocket-like cusps of the aortic valve, and is stopped by aortic valve closure, MP3). Similarly, as the pressure in the right ventricle falls below the pressure in the pulmonary arterythe pulmonary valve closes. The S 2 sound results from reverberation within the blood associated with the sudden block of flow reversal.
Splitting of S2also known as physiological split, normally occurs during inhalation because the decrease in intrathoracic pressure increases the time needed for pulmonary pressure to exceed that of the right ventricular pressure.
A widely split S2 can be MP3) with several different cardiovascular conditions, including Right bundle branch blockpulmonary stenosisand atrial septal defect. Pulmonary S2 P2 will be accentuated loud P2 in pulmonary hypertension and pulmonary embolism. S2 becomes softer in aortic stenosis. The rarer extra heart sounds form gallop rhythms and are heard in both normal and abnormal situations.
It occurs at the beginning of diastole after S2 and is lower in pitch than S1 or S2 as it is not of valvular origin. The third heart sound is benign in youth, some trained athletes, and sometimes in pregnancy but if it re-emerges later in life it may signal cardiac problems, such as a failing left ventricle as in dilated congestive heart failure CHF.
S3 is thought to be caused by the oscillation of blood back and forth between the walls of the ventricles initiated by blood rushing in from the atria. The reason the third heart sound does not occur until the middle third of diastole is probably that during the early part of diastole, the ventricles are not filled sufficiently to create enough tension for reverberation. It may also be a result of tensing of the chordae tendineae during rapid filling and expansion of the ventricle.
In other words, an S3 heart sound indicates increased volume of blood within the ventricle. An S3 heart sound is best heard with the bell-side of the stethoscope used for lower frequency sounds.
A left-sided S3 is best heard in the left lateral decubitus position and at the apex of the heart, which is normally located in the 5th left intercostal space at the midclavicular line. A right-sided S3 is best heard at the lower-left sternal border. The way to distinguish between Dubbing - Various - The Sound Of Nature 2 (File left and right-sided S3 is to observe whether it increases in intensity with inhalation or exhalation.
A right-sided S3 will increase on inhalation, while a left-sided S3 will increase on exhalation. S3 can be a normal finding in young patients but is generally pathologic over the age of Register Log In. UI Confirmation Alert, A2.
