What does a horses heart sound like?
Moderately loud murmur with some radiation (similar intensity to S1 and S2) Very loud murmur that radiates widely (louder than S1 and S2) Very loud murmur with a palpable thrill. Very loud murmur with a thrill that is audible with the stethoscope off the chest wall.
What does a horse heart murmur sound like?
Cardiology. The third heart sound or S3 is a rare extra heart sound that occurs soon after the normal two lub-dub heart sounds (S1 and S2). S3 is associated with heart failure
What does S3 sound indicate?
The best place to listen to the heart is just behind the elbow (see picture). The heart can be heard on either side, but is often louder on the left side. The horse has a large heart and a slow resting heart rate. When you listen you will hear a lub and then a dub sound followed by a pause.

How many heart sounds do horses have?
However, there are actually four heart sounds, though not all of them can be heard in every horse. Each sound relates to a different event in the cardiac cycle. To understand what these sounds relate to, it is necessary to understand some anatomy of the heart.

How do you tell if a horse has a heart murmur?
Symptoms of a heart murmur may include:
What does an abnormal heart murmur sound like?
A heart murmur is a sound caused by blood flow within the heart. Instead of ‘lub-dub’, the heartbeat may have an added sound like a hum, a whoosh or a rasp. The cause of the whooshing sound is the vibration of blood as it moves through the heart, which is normally undetectable by stethoscope.
How long can horses live with a heart murmur?
They may range from grade 1-6/6, but most horses have a murmur that is grade 1-3/6, if it can be heard, Reef says. It is more likely to be associated with congestive heart failure, with a poor to grave prognosis for life, about 3-6 months with supportive therapy.
Can a heart murmur make noise?
Doctors hear a heart murmur as a whooshing sound between heartbeats. The whoosh is just an extra noise that the blood makes as it flows through the heart.
What does the S3 sound represent?
CLINICAL PEARL: A S3 heart sound is often a sign of systolic heart failure, however it may sometimes be a normal finding. A S3 can be an important sign of systolic heart failure because, in this setting, the myocardium is usually overly compliant, resulting in a dilated LV; this can be seen in the image below.
What causes the S3 heart sound?
The third heart sound (S3), also known as the ventricular gallop, occurs just after S2 when the mitral valve opens, allowing passive filling of the left ventricle. The S3 sound is actually produced by the large amount of blood striking a very compliant left ventricle
What does an S3 murmur indicate?
Third Heart Sound S3 Results from increased atrial pressure leading to increased flow rates, as seen in congestive heart failure, which is the most common cause of a S3. Associated dilated cardiomyopathy with dilated ventricles also contribute to the sound.
How many heart sounds in a horse?
All four heart sounds (S1, S2, S3, S4) are audible in healthy horses. Intensity varies with duration of diastolic filling and sympathetic stimulation. S1 is early ventricular contraction, AV closure, ejection w/semilunar opening.
What are the 4 sounds of the heart?
What are the four heart sounds?
- First sound. When the two ventricles contract and pump out blood into the aorta and pulmonary artery the mitral and tricuspid valves close to prevent the blood flowing back into the atria.
- Second sound.
- Third sound.
- Fourth sound.
Can you hear all 4 heart sounds?
The best place to listen to the heart is just behind the elbow (see picture). The heart can be heard on either side, but is often louder on the left side. The horse has a large heart and a slow resting heart rate. When you listen you will hear a lub and then a dub sound followed by a pause.
How many heart valves does a horse have?
Heart valves sit between each atrium and its respective ventricle and between the ventricle and the major vessel it supplies. There are four heart valves and these are thin sheets of tissue that open and close to allow the heart to fill and then empty at the appropriate time.
Where do you listen to heart sounds on a horse?
The best place to listen to the heart is just behind the elbow (see picture). The heart can be heard on either side, but is often louder on the left side. The horse has a large heart and a slow resting heart rate. When you listen you will hear a lub and then a dub sound followed by a pause.
Where on the horse is the heart best heard?
The location of a murmur is where it is heard loudest, or the point of maximal intensity (PMI). This is generally described as left or right and apical or basilar. In horses, it may be possible to further differentiate the pulmonic valve area from the aortic valve area at the left heart base.
Where is the heart of a horse located?
A horse heart is located in the same place as a human heart: between the lungs and ribs and above the diaphragm. A horse heart weighs on average seven to nine pounds.
Where do you hear S3 and s4?
Like S3, the S4 sound is low pitched and best heard at the apex with the patient in the left lateral decubitus position.
Is a heart murmur serious in horses?
They may range from grade 1-6/6, but most horses have a murmur that is grade 1-3/6, if it can be heard, Reef says. It is more likely to be associated with congestive heart failure, with a poor to grave prognosis for life, about 3-6 months with supportive therapy.
What does a heart murmur sound like in a horse?
When this occurs the horse goes into acute, severe heart failure and almost inevitably dies. Horses are prone to physiological murmurs as they have such large hearts and large blood vessels, so some turbulent blood flow is not surprising. These murmurs are of no clinical significance
What causes heart murmur in horses?
Moderately loud murmur with some radiation (similar intensity to S1 and S2) Very loud murmur that radiates widely (louder than S1 and S2) Very loud murmur with a palpable thrill. Very loud murmur with a thrill that is audible with the stethoscope off the chest wall.
How do you know if you have an abnormal heart murmur?
An abnormal heart murmur may cause the following signs and symptoms, depending on the cause of the murmur: Skin that appears blue, especially on your fingertips and lips. Swelling or sudden weight gain. Shortness of breath.
