The Still heart murmur is the most common benign murmur occurring in childhood. First described by George Still in 1909, it can be auscultated at any time during childhood but most commonly presents between age 2 and 6 years.
The Still murmur is best heard during early systole along the left lower border of the sternum and is usually rated as a 1-2 out of 6 in intensity. It is usually described as a low-pitched, twangy, vibratory finding sometimes with a “musical” quality to it.
The classic finding of a Still murmur is that it decreases in intensity when a child moves from a supine to standing position, which is not found in pathological murmurs.
