What is a Cardiac Murmur?
As blood passes through the heart, it produces a thumping “lub-dub” sound. If there are any additional sounds, this is referred to as a cardiac murmur.
A cardiac murmur is a common occurrence – experts estimate that a murmur can be detected at some point in 90 percent of children between 4 and 7 with normally functioning hearts. It can either be caused when blood flows through a faulty heart valve or from a condition that increases the heartbeat rate, forcing the heart to compromise and handle more blood than usual.
Some babies are born with heart valve issues and in rare cases, cardiac murmurs may be associated with a damaged valve in the heart. However, in most cases, murmurs are considered harmless and do not require treatment.
