when a heart murmur is heard through a stethoscope, it make a faint " hiss sound. which pair of valves are not closing properly
Added by Sandra E.
Step 1
A heart murmur is an abnormal sound heard during a heartbeat, and it can be caused by various factors, including improper closing of heart valves. The "hiss" sound suggests a high-pitched murmur, which is often associated with blood flowing through narrowed or Show more…

Heart murmurs caused by a stenotic mitral valve are heard as a high pitched click when the valve should be—but is not—wide open during systole. They are detected due to the turbulent blood flow that occurs as blood backflows into the left atrium. They are also detected if the valve's cusps are thin and flexible. All of the listed responses are true.

Heart murmurs caused by a stenotic mitral valve ______. Choose the correct answer: A) are heard as a high-pitched click when the valve should be—but is not—wide open during systole. B) are detected due to the turbulent blood flow that occurs as blood backflows into the left atrium. C) are detected if the valve's cusps are thin and flexible. D) All of the listed responses are true.
Adi S.
If a person has a heart murmur caused by the improper opening and closing of a heart valve, the ECG or heart sounds (choose one) will be unusual as the blood is forced through a more narrow opening (stenotic valve), or the blood backflows because the valve does not close properly (incompetent valve). Explain your reasoning for the answer choice.
