The murmur is low intensity, high-pitched, best heard over the left sternal border or over the right second intercostal space, especially if the patient leans forward and holds breath in full expiration. The radiation is typically toward the apex. The configuration is usually decrescendo and has a blowing character.
How can you describe murmurs in a cardiovascular examination?
Murmurs are described by their timing in the cardiac cycle, intensity, shape, pitch, location, radiation and response to dynamic maneuvers. Using the aforementioned criteria, a clinician can accurately characterize the nature of a murmur and communicate their findings in a precise manner.
How do nurses describe normal heart sounds?
Heart rate and rhythm are normal. No murmurs, gallops, or rubs are auscultated. S1 and S2 are heard and are of normal intensity.
How does 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 do you describe a still murmur?
Still’s Murmur describes a benign “twangy” (like a string being plucked) medium-to-long ejection systolic murmur, heard loudest at the left lower sternal border and apex, most commonly heard in children. The murmur increases in intensity with high output states, such as fever, anxiety, and exercise.
Where do you hear a murmur?
Mitral murmurs are best heard at the apex and radiate to the axilla. Mitral sounds can be accentuated with the patient in the left lateral position. Hence, to listen to a mitral murmur, first listen to the apex, then listen round to the mid-axillary line at the same level.
How do you hear a murmur?
You will need to listen to the heart with the bell of your stethoscope to hear the abnormal heart sounds. To hear a ventricular gallop, or S3, you should listen over the mitral valve with the bell. It will sound like a weird plopping noise right after you hear the “dub”.
What are the 5 heart sounds?
The 5 points of auscultation of the heart include the aortic, pulmonic, tricuspid, and mitral valve as well as an area called Erb’s point, where S2 is best heard.
How do you describe a heart sound?
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 are the four types of heart murmurs?
- 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.

How do you assess heart sounds?
Listen over the aortic valve area with the diaphragm of the stethoscope. This is located in the second right intercostal space, at the right sternal border (Figure 2). When listening over each of the valve areas with the diaphragm, identify S1 and S2, and note the pitch and intensity of the heart sounds heard.
What are abnormal heart sounds?
Abnormal heart sounds are called heart murmurs. These sounds can include rasping, whooshing, or blowing sounds. Heart murmurs can occur during different parts of your heartbeat.
How do you write normal heart sounds?
Auscultation: Normal S1 and S2, with regular rate and rhythm. S2 > S1 at the base, S1 > S2 at apex. No splitting of the heart sounds heard.
What type of murmur is considered innocent?
The most common type of heart murmur is called functional or innocent. An innocent heart murmur is the sound of blood moving through a normal, healthy heart in a normal way.
What kind of murmur is a still's murmur?
Still’s murmur (a.k.a. “innocent murmur” or “functional murmur”) refers to a benign flow murmur across the aortic valve from high cardiac output and/or increased contractility (inotropy). Frequently seen in the pediatric population, Still’s murmur can disappear as the person moves into adolescence.
What is the most common innocent murmur?
By far and away the Still’s murmur is the most common innocent heart murmur.
Can you always hear a heart murmur?
Myth #2: You can tell it’s a murmur just by listening Not always. Many times, people are referred to a cardiologist because their primary care physician hears a murmur.
What is a thrill heart sound?
A thrill is a vibratory sensation felt on the skin overlying an area of turbulence and indicates a loud heart murmur usually caused by an incompetent heart valve.
What type of word is murmur?
Murmur is commonly used as a both a verb and a noun. Most of its senses involve a low, indistinct sound.
How are murmurs graded?
GRADES. Systolic murmurs are graded on a six-point scale. A grade 1 murmur is barely audible, a grade 2 murmur is louder and a grade 3 murmur is loud but not accompanied by a thrill. A grade 4 murmur is loud and associated with a palpable thrill.
Is s4 a murmur?
Fourth heart soundOther namesAtrial gallop, presystolic gallopDiagram of the heart.SpecialtyCardiology
Where are heart sounds best heard?
CLINICAL PEARL: A split S1 heart sound is best heard at the tricuspid listening post, as T1 is much softer than M1. The M1 sound occurs slightly before T1. Because the mitral and tricuspid valves normally close almost simultaneously, only a single heart sound is usually heard.
Where do you hear S1 the loudest?
The 1st heart sound, S1 (lub), marks the beginning of systole (end of systole). Related to the closure of the mitral and tricuspid valves. Loudest at the apex.
Which is worse diastolic or systolic murmur?
The four most commonly encountered diastolic murmurs include aortic and pulmonary valve regurgitation, and mitral and tricuspid valve rumbles (Table 27.1). Compared to most systolic murmurs, diastolic murmurs are usually more difficult to hear, and certain auscultatory techniques are essential for their detection.
Can you hear heart murmur without stethoscope?
Grade I murmurs may not be audible to the inexperienced examiner; however, grade 6 murmurs are heard even without the stethoscope on the chest and may actually be visible. Diastolic murmurs are graded on a scale of 4.
Can a heart murmur be fixed?
Surgeries for heart murmurs often include valve repair and valve replacement. These surgeries treat the underlying valve problems in your heart that are causing the murmur. If you do need surgery, your cardiothoracic surgeon will try to make sure your surgery is as minimally invasive as possible.
How can you tell the difference between a systolic and diastolic murmur?
Systolic murmur – occurs during a heart muscle contraction. Systolic murmurs are divided into ejection murmurs (due to blood flow through a narrowed vessel or irregular valve) and regurgitant murmurs. Diastolic murmur – occurs during heart muscle relaxation between beats.
What do S1 and S2 sounds represent?
Heart Sounds S1 is normally a single sound because mitral and tricuspid valve closure occurs almost simultaneously. Clinically, S1 corresponds to the pulse. The second heart sound (S2) represents closure of the semilunar (aortic and pulmonary) valves (point d).
What is an S3 murmur?
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 are 3 abnormal heart sounds?
- S1 (e.g., mitral stenosis, atrial fibrillation)
- S2 (e.g., hypertension, aortic stenosis)
- S3 (e.g., congestive heart failure)
- S4 (e.g, hypertension)
- Abnormal splitting (e.g., atrial septal defect)
What is a 2 6 murmur?
Grade 2/6 – Audible, but faint. Grade 3/6 – Easily heard. Grade 4/6 – Very easily heard. Grade 5/6 – Very loud. Grade 6/6 – Can be heard without the stethoscope being in contact with the chest wall.
