Heart sounds of a ventricular septal defect in a 14-year-old girl. A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle.
Heart murmurs are unique heart sounds produced when blood flows across a heart valve or blood vessel. [1] This occurs when turbulent blood flow creates a sound loud enough to hear with a stethoscope. [2] The sound differs from normal heart sounds by their characteristics. For example, heart murmurs may have a distinct pitch, duration and timing.
These are the first heart sound (S 1) and second heart sound (S 2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs , adventitious sounds , and gallop rhythms S 3 and S 4 .
A murmur is an extra heart sound that can be heard by a stethoscope. Sometimes, a murmur sounds like a humming sound, which can be faint or loud. It might be temporary or persistent. Heart murmurs ...
Heart sounds of a ventricular septal defect patient. The condition consists of atresia affecting the pulmonary valve and a hypoplastic right ventricular outflow tract. The ventricular septal defect doesn't impede the in and outflowing of blood in the ventricular septum, which helps it form during fetal life. [3] [5]
A harsh murmur usually on left second intercostal space radiating to left neck and accompanied by palpable thrill. It can be distinguished from a VSD (ventricular septal defect) by listening to the S2, which is normal in VSD but it is widely split in pulmonary stenosis. However, VSD is almost always pansystolic where the murmur of pulmonary ...
