Where do you Auscultate for a heart murmur?
1. Auscultate the heart at various sites
- At the apex.
- At the base (the part of the heart between the apex and the sternum)
- In the aortic and pulmonary areas to the right and left of the sternum, respectively.
How do you Auscultate a murmur?
Mitral murmurs
- 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.
- Note the timing of any murmur.
How would you describe the sound of a heart murmur?
A heart murmur is a blowing, whooshing, or rasping sound heard during a heartbeat. The sound is caused by turbulent (rough) blood flow through the heart valves or near the heart.
How do you assess a heart murmur?
Tests
- Echocardiogram. This is the main test used to determine the cause of a heart murmur.
- Chest X-ray. A chest X-ray is a picture of the heart and lungs.
- Electrocardiogram (ECG or EKG). This quick and painless test measures the electrical activity of the heart.
- Cardiac catheterization.
What are the 5 points of auscultation?
The locations of auscultation center around the heart valves. The aortic, pulmonic, tricuspid, and mitral valves are four of the five points of auscultation. The fifth is Erb’s point, located left of the sternal border in the third intercostal space.
How do you know if a murmur is systolic or diastolic?
Systolic murmurs occur between the first heart sound (S1) and the second heart sound (S2). Diastolic murmurs occur between S2 and S1. In addition, timing is used to describe when murmurs occur within systole or diastole.
What are 3 abnormal heart sounds?
Abnormal Heart Sounds and Murmurs – 62
- S1 (e.g., mitral stenosis, atrial fibrillation)
- S2 (e.g., hypertension, aortic stenosis)
- S3 (e.g., heart failure)
- S4 (e.g., hypertension)
- Abnormal splitting (e.g., atrial septal defect)
What are the four types of heart murmurs?
What Are the Different Types of 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.
What are the 4 areas of heart auscultation?
The four standard points of auscultation for the heart are: Aortic – on the patients right side of the sternum. Pulmonary – on the left-hand side of the patients’s sternum. Tricuspid – in the fourth intercostal space, along the lower-left border of the sternum.
What order do you Auscultate heart sounds?
Where to listen for Heart Sounds (Auscultory Areas) – MEDZCOOL
What does a VSD sound like?
A loud, harsh, holosystolic murmur at the lower left sternal border is common. Recurrent respiratory infections and heart failure may develop. Diagnosis is by echocardiography. Defects may close spontaneously during infancy or require surgical repair.
What is the most common heart murmur?
The most common type of heart murmur is called functional or innocent. An innocent heart murmur is the sound of blood moving through a healthy heart in a normal way.
What does an ASD sound like?
The increased blood flow to the lungs creates a swishing sound, known as a heart murmur. The murmur, along with other specific heart sounds, often is the first tip-off to a doctor that a child has an ASD. ASDs can be in different places on the atrial septum and can vary in size.
What does aortic stenosis sound like?
The typical murmur of aortic stenosis is a high-pitched, “diamond shaped” crescendo-decrescendo, midsystolic ejection murmur heard best at the right upper sternal border radiating to the neck and carotid arteries (see figure below). In mild aortic stenosis, the murmur peaks in early systole.
What does a PDA sound like?
The murmur of a PDA is described as a medium pitched high-grade continuous murmur heard best at the pulmonic position, with a harsh machinelike quality that often radiates to the left clavicle.
What does mitral stenosis sound like?
The diastolic murmur of mitral stenosis is of low pitch, rumbling in character, and best heard at the apex with the patient in the left lateral position. It commences after the opening snap of the mitral valve, and the duration of the murmur correlates with the severity of the stenosis.
What does a mitral regurgitation murmur sound like?
The murmur of mitral regurgitation is described as a high-pitched, “blowing” holosystolic murmur best heard at the apex. Although the direction of radiation of the murmur depends on the nature of the mitral valve disease, it usually radiates to the axilla.
When is a diastolic murmur heard?
Diastolic heart murmurs are heart murmurs heard during diastole, i.e. they start at or after S2 and end before or at S1. Many involve stenosis of the atrioventricular valves or regurgitation of the semilunar valves.
What does a tricuspid murmur sound like?

When do you hear a systolic murmur?
A systolic murmur is a murmur that begins during or after the first heart sound and ends before or during the second heart sound.
What does systolic murmur sound like?
Overview. Heart murmurs are sounds — such as whooshing or swishing — made by rapid, choppy (turbulent) blood flow through the heart. The sounds can be heard with a device called a stethoscope. A typical heartbeat makes two sounds like “lubb-dupp” (sometimes described as “lub-DUP”) when the heart valves are closing.
