![]() If you hear a murmur, completely assess it with regards to its timing, duration, location, intensity, pitch, character, radiation, change with position and respiration. These are common in acquired and congenital heart disease, and are a useful diagnostic tool. The S 1 heart sound represents the mitral and tricuspid valves closing before the contraction of the ventricle. Then auscultate for “added sounds” (Murmurs, Clicks, Opening Snaps & Pericardial rubs). Any unusual heart sound is called a murmur. You should first concentrate only on “heart sounds” (carefully assess their intensity & splitting). Other heart sounds include a galloping rhythm, which involves additional heart sounds, S3 and S4: An S3 gallop or third heart sound is a sound that occurs after the diastole S2 dub. But starting from Apex and proceeding with Tricuspid (LLSB), Aortic & Pulmonic areas is easy to practice. There is no standard order for auscultation. You should firmly press your “diaphragm” to chest wall whereas apply only light pressure when you are auscultating with the “bell” of your stethoscope.

Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Apart from the 3rd and 4th heart sounds and the mid-diastolic murmur of Mitral Stenosis, all the other heart sounds are best heard with the diaphragm of your stethoscope.

There are four valves in the heart: two atrioventricular (AV) valves and two semilunar valves. Use your stethoscope for cardiac auscultation. Heart sounds occur from the closing of heart valves, just like a door slamming shut, and the sound is transmitted in the direction of blood flow. Some cardiac sounds can be heard with the unaided ear (e.g. Heart sounds are produced by the vibrations of the cardiohemic system, composed of the blood, heart walls, and valves. The 'dupp' sound is made by the semilunar valves closing. The 'lub' sound is made by the contraction of the ventricles and the closing of the atrioventricular valves. ![]() ![]() These sounds are referred to as the 'lub-dupp' sounds. Auscultation for heart sounds is mainly done in 4 areas, namely Mitral, Tricuspid, Aortic & Pulmonic. Remember these areas do not correspond to the location of heart valves, but the areas where the cardiac sounds are best heard. Heart Sounds The audible sounds that can be heard from the heart are made by the closing of the heart valves. ![]()
