What are the classifications of heart murmurs?
Types of murmurs include the following:
- Systolic murmur. A heart murmur that occurs during a heart muscle contraction. …
- Diastolic murmur. A heart murmur that occurs during heart muscle relaxation between beats. …
- Continuous murmur. A heart murmur that occurs throughout the cardiac cycle.
What are the four types of heart murmurs?
What are the different types of murmurs?

What are two general classifications of murmurs?
Types of murmurs include:
Diastolic murmur – occurs during heart muscle relaxation between beats. Diastolic murmurs are due to a narrowing (stenosis) of the mitral or tricuspid valves, or regurgitation of the aortic or pulmonary valves. Continuous murmur – occurs throughout the cardiac cycle.
How are cardiac murmurs graded?
Heart sounds and murmurs.
…
…
| Grade 1 | Faintest sound that can be detected; often detected by cardiologists but not by general clinicians |
|---|---|
| Grade 2 | Soft murmur that is readily detectable |
| Grade 3 | Louder than grade 2 but not associated with a palpable thrill |
| Grade 4 | Easily detected murmur associated with a palpable thrill* |
What are 3 abnormal heart sounds?

- Abnormal heart sounds.
- Systolic murmurs.
- Diastolic murmurs.
- Pericardial friction rubs.
What type of murmur is mitral stenosis?
Mitral stenosis results in a uniquely shaped, low-pitched diastolic murmur best heard at the cardiac apex.
What are the 4 heart sounds?
In a healthy adult, the heart makes two sounds, commonly described as ‘lub’ and ‘dub. ‘ The third and fourth sounds may be heard in some healthy people, but can indicate impairment of the heart function. S1 and S2 are high-pitched and S3 and S4 are low-pitched sounds.
What is a grade 4 murmur?
A grade 4 murmur is loud and associated with a palpable thrill. A grade 5 murmur is associated with a thrill, and the murmur can be heard with the stethoscope partially off the chest. Finally, the grade 6 murmur is audible without a stethoscope. All murmurs louder than grade 3 are pathologic.
What is a 3 out of 6 heart murmur?
Grade 3 refers to a murmur that is moderately loud, and grade 4 to a murmur that is very loud. A grade 5 murmur is extremely loud and is audible with one edge of the stethoscope touching the chest wall. A grade 6 murmur is so loud that it is audible with the stethoscope just removed from contact with the chest wall.
What is the most common cause of a heart murmur?
In adults, worrisome heart murmurs are usually due to heart valve problems that develop later in life (acquired heart valve disease). Things that can damage the heart valves include: Calcium deposits.
Which is worse diastolic or systolic murmur?
Providers grade diastolic heart murmurs on a scale of one through four, with one being the faintest and four being the loudest. They grade systolic murmurs on a scale of one through six, with one being the faintest murmur and six being the loudest.
Do heart murmurs get worse with age?
Likewise, murmurs can get worse if a condition goes untreated or becomes more serious. Your heart is unique, and some heart murmurs can change over time.

Which murmurs are louder on expiration?
At its release, murmurs of HOCM and mitral insufficiency can be heard to get louder. Respiration: right-sided murmurs tend to be louder on inspiration, left-sided murmurs tend to be louder on expiration. This can be remembered with R-I-L-E (right on inspiration, left on expiration).
What type of murmur is pulmonary stenosis?
The heart murmur of pulmonary stenosis is a choppy noise caused by ejection of blood through the obstructed valve. There is often an associated click sound when the thickened valve snaps to its open position.
