Flashcards

Aortic stenosis murmur location

Heard at the aortic area during the systolic phase of the heartbeat, often associated with narrowed aortic valve.

Tricuspid regurgitation murmur location

Heard at the tricuspid area during the systolic phase and caused by leaking tricuspid valve.

Mitral regurgitation murmur location

Heard at the mitral area during a systolic heartbeat; indicates leakage in the mitral valve.

Aortic regurgitation murmur location

Heard at the left sternal border during the diastolic phase of the heartbeat; implicates leaky aortic valve.

Where is a murmur of aortic stenosis heard?

Aortic stenosis murmur is heard in the aortic area, specifically during the systolic phase of the heartbeat.

What does a murmur at the mitral area during systole indicate?

A murmur at the mitral area during systole suggests mitral regurgitation. This means the mitral valve is not closing properly, allowing blood to flow back into the left atrium during ventricular contraction.

What is a flow murmur?

A flow murmur is a harmless, common murmur caused by normal blood flow through the heart. It's often described as a 'physiological murmur'.

Where can a murmur of tricuspid stenosis be heard?

A murmur of tricuspid stenosis is heard at the tricuspid area, during the diastolic phase of the heartbeat.

Which valve problem results in a murmur heard at the left sternal border during diastole?

Aortic regurgitation, a condition where the aortic valve leaks during diastole, results in a murmur heard at the left sternal border.

Systolic Murmur Location

A systolic murmur is heard during the contraction phase of the heart (between heartbeats). The location of the murmur can help pinpoint the affected heart valve.

Diastolic Murmur Location

A diastolic murmur is heard during the relaxation phase of the heart (between heartbeats). It indicates a valve problem during the heart's 'rest' period.

Aortic Stenosis Location

Aortic stenosis is a narrowing of the aortic valve, causing a murmur heard at the aortic area during systole.

Mitral Regurgitation Location

Mitral regurgitation, a leaking mitral valve, produces a systolic murmur heard at the mitral area (left side of the chest).

Tricuspid Stenosis Location

Tricuspid stenosis, a narrowing of the tricuspid valve, causes a diastolic murmur heard at the tricuspid area (lower right side of the chest).

What causes a murmur at the aortic area?

Aortic stenosis, a narrowed aortic valve, can cause a murmur at the aortic area during the systolic phase of the heartbeat. Other potential causes include flow murmurs, which are often harmless, and aortic valve sclerosis.

Tricuspid Regurgitation

Tricuspid regurgitation is a condition where the tricuspid valve leaks during the systolic phase of the heartbeat, causing a murmur heard at the tricuspid area.

Where is a murmur of mitral stenosis heard?

A murmur of mitral stenosis is heard at the mitral area during the diastolic phase of the heartbeat. It's caused by a narrowed mitral valve.

Hypertrophic Cardiomyopathy Murmur

Hypertrophic cardiomyopathy, a thickening of the heart muscle, can cause a murmur heard at the left sternal border during the systolic phase of the heartbeat.
