I was the one to speak first, proposing that my companions should sup with me, not across the way, which would be riotous with more than one infernal supper, but in another much more select establishment in a side street away from the Cannebiere.
A heart murmur is a sound that is created by inadequate blood flow through the heart and its large vessels, for example the aorta. Some are born with a heart murmur and further testing doesn't reveal any significant problem. This is called a physiological murmur. http://www.5min.com/Video/What-is-Innocent-Heart-Murmur-5501
Complicated: A 'heart murmur means that one can hear blood flow with a stethoscope. Very nonspecific term. A hole in the heart is a connection between the circulation that supplies the lungs (right heart) and the circulation that supplies the body (left heart). There are various types of holes (defects). All of the holes/defects have the potential to cause a murmur.
