Pulmonary ejection murmur


 * systolic functional heart murmur, physiological, innocent
 * it is caused by the rapid expulsion of blood in the lung
 * characteristic: pronounced (up to 3/6), blowing character, softer than a vibrating rustle
 * listening maximum: left upper edge of sternum
 * it changes with position - it is better heard lying down than standing up
 * intensifies during exertion, fever, anemia and poor posture, which leads to the heart moving closer to the front wall of the chest
 * is similar to the auscultatory finding in a secundum-type atrial septal defect – murmurs can be differentiated by the split of the second sound above the lung: in an innocent murmur, the split is only in inspiration, in the case of an atrial septal defect, the split is constant
 * incidence: asthenic children with a weak chest wall
