So if you look at a stethoscope it’s actually angled a certain way. And whenever I watch doctors on TV they always put it in backward and it drives me crazy cuz no doctor would put it in backward. “oh, I’m gonna listen” You can’t hear anything. It points towards the nose. Right here. There it is. Now I can hear just fine. Hello Really loud. Hello Today, I’m going to talk to you about murmurs in your pets. Heart murmurs. Not just murmur, murmur, murmur, murmur, murmur, murmur. There could be a systolic murmur. That’s the most common. There could be a diastolic murmur. Less common. And even less common would be a patent ductus arteriosus. Heart murmur, very simply, is an abnormal sound in the heart. That’s it. Instead of a nice, lub-dub, lub-dub, lub-dub I hear woosh-dub, woosh-dub, woosh-dub, woosh dub. But you won’t hear that. You know why? You don’t have one of these. Only doctors have these. Can’t just buy that. The interesting about it is a heart murmur doesn’t actually tell me anything about how the heart is functioning, most of the time. It does tell me that there may be some abnormal blood flow in there. There’s a lot of reasons we can see it in cats. a common one is Hyperthyroidism that there There thyroid gland gets overactive and makes the heart beat really fast and it doesn’t quite keep up. A very common one I will see is really small dogs will have valve problems. So, instead of their valves closing nice and smooth like that. They actually get little knobbly and they look like that. and you can see little holes through them. The valve’s not closing very well and blood sort of flows back and forth. and so when that big left ventricle contracts instead of it all the blood going out through the body like it should some of it goes back into the left atrium. and so that left atrium gets bigger and bigger and bigger. So we have back-up of blood. and if it keeps backing up, it will back up even farther into the lungs. That’s called congestive heart failure. By the time we get to the place where it’s causing congestive heart failure the things you’re going to notice are being short of breath, exercise intolerance, in other words, dogs that normally would run after the ball, they get out of breath really fast. Not wanting to eat in cats is a big one. Occasionally you’ll see dogs that have a cough and that could be because they have fluid in their lungs or it might be because that left atrium is getting bigger and bigger and bigger and it’s actually pushing on the main stem bronchi and causing them to get smooshed a little bit and causing a little bit of bronchitis. There are a lot of dogs out there that have heart murmurs and they never ever cause a problem They just sit there. They call them innocent murmurs. They’ve been there forever. Very often we’ll see puppies with an innocent murmur that goes away at about 12-16 weeks of age. So if a puppy comes in and I hear a slight murmur I don’t get too worried. I don’t send them straight to the cardiologist. I’ll usually say, “this one’s okay. Lets just check it in a few weeks and often they’ll go away. There are some specific murmurs that can indicate a big problem. and one of those is in very young dogs. You’ll hear a murmur that actually sounds like a washing machine. And that’s something we usually recommend go to see a cardiologist right away Thanks for watching. I hope that helps to answer all the questions you have about heart murmurs in your pets.
