Heart Sounds. Heart sounds are generated by the turbulance created by blood flowing through the heart, specifically when the heart valves close. Normal heart sounds can be characterized by a lub dub that occurs with a heart beat. The first heart sound (lub) occurs when the atrioventricular (AV) valves close and the second heart sound (dub) is heard when the semilunar valves close.
1. Explain why ventricular contraction (systole) and the 'lub' sound occur immediately after the QRS complex. The lub sound occurs during the beginning stages of systole (ventricular contraction) and when the atrioventricular valves, which prevents blood from flowing back into the atria. The QRS complex is the first heart beat of the cycle, so directly after the heart beat or QRS complex, the valves close to prevent backflow and makes the âlubâ sound. 2. Explain why ventricular relaxation (diastole) and the 'dup' sound occur after the T wave. The T wave is the wave produced by the relaxation of the ventricles, which causes the blood pressure to drop and when the semilunar valves close, the âdupâ sound is made. 3.
