Since the L ventricle has a higher pressure than the R ventricle, flow during systole occurs from the L to R ventricle, producing the holosystolic murmur. It can be best heard over the left third and fourth intercostal spaces and along the sternal border. It is associated with normal pulmonary artery pressure and thus S2 is normal.
It is best heard at the left upper sternal border. This is the result of an increased volume going through the pulmonary valve. It has association with a fixed, split S2 and a right ventricular heave. Ventricular septal defect (VSD) will present as a holosystolic murmur. One can hear it at the left lower sternal border.
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.
It extends from a point in the second left intercostal space, about 2.5 mm. from the sternal margin, obliquely downward, with a convexity to the left, to the apex of the heart. This is contrasted with the acute margin of the heart, which is at the border of the anterior and posterior surface, and in which the acute marginal branch of the right ...
The normal apex beat can be palpated in the precordium left 5th intercostal space, half-inch medial to the left midclavicular line and 3–4 inches left of left border of sternum. In children the apex beat occurs in the fourth rib interspace medial to the nipple.
The murmur is heard best with the bell of the stethoscope [16] lying on the left side [15] and its duration increases with worsening disease. [16] Advanced disease may present with signs of right-sided heart failure such as parasternal heave , jugular venous distension , hepatomegaly , ascites and/or pulmonary hypertension (presenting with a ...

Also, that blood flowing through a VSD can be heard as a holosystolic murmur at the lower left sternal border. If it’s a small VSD, it might be asymptomatic. As the size of the VSD increases, though, symptoms tend to get more severe and present earlier on in life.
