A heart murmur should be assessed for which of the following? Select all that apply.

A. The timing of the murmur (systolic or diastolic) is an essential component of murmur assessment. It helps in determining the cause of the murmur, whether it’s related to heart valves or flow. B. Radiation refers to where the murmur can be heard best, or if it radiates to other parts of the chest or neck, helping to indicate the origin of the murmur. C. Fremitus is a term used to describe the vibrations felt on the chest wall when a person speaks, which is unrelated to heart murmurs. D. Egophony refers to an abnormal lung sound heard during auscultation and is not relevant to the assessment of a heart murmur. E. The location where the murmur is heard best on the chest wall is crucial in determining its origin, such as whether it is coming from the aortic or mitral valve.
