Other Innocent Murmurs

You are incorrect - the best description of the acoustic events at the upper right sternal edge is a continuous murmur louder in diastole.

Your choice: continuous, louder in systole

This is a graphic example of a continuous murmur that is louder in systole. Note that the murmur is quite rough and noisy, particularly in systole. This murmur cannot be altered by neck vein compression, turning the head or moving the patient to the supine position. This murmur is characteristic of a patent ductus arteriosus.
