Hearts are pretty incredible organs. Most of us are lucky that our hearts function without any complications but not everybody is so fortunate. One of these complications is a heart murmur. A heart murmur is a whooshing sound from the heart that is caused by a turbulent blood flow 1.
Heart murmurs are heart sounds produced when blood is pumped across a heart valve and creates a sound loud enough to be heard with a stethoscope. There are two types of murmurs. A functional murmur or " physiologic murmur" is a heart murmur that is primarily due to physiologic conditions outside the heart. Other types of murmurs are due to structural defects in the heart itself. Functional murmurs are benign an " innocent murmur ".
A heart murmur is the sound of blood flow turbulence in the heart. Some heart murmurs are innocent while others may require referral for additional medical tests. This video provides an animated view of a heart murmur. While playing the animation, notice the heart valves and blood flow.
A feline heart murmur is usually detected during the course of a routine exam when the vet listens to your cat's heart using a stethoscope. It simply means the heart is making unusual sounds that could indicate an abnormality. If your vet determines that your cat has a heart murmur, you'll want to understand what causes the condition, how serious it is, and what your next steps might be. A heart murmur occurs when there's turbulence in the blood as it flows through the heart.
