Millwheel murmur意思
"Millwheel murmur" is a term used in medicine to describe a specific type of heart murmur that is caused by the closure of the aortic or pulmonic valves. This term is used to describe the sound that is similar to the sound of a millwheel, which is a large wheel that is turned by the force of water in a mill. The sound is characterized by a whooshing or swishing sound that is heard in the heart during the systolic phase, which is when the heart is contracting.
There are two types of millwheel murmur:
-
Aortic millwheel murmur: This type of murmur is caused by the closure of the aortic valve, which is the valve that separates the left ventricle from the aorta. The sound is often described as a loud, blowing sound that is heard best at the base of the heart.
-
Pulmonic millwheel murmur: This type of murmur is caused by the closure of the pulmonic valve, which is the valve that separates the right ventricle from the pulmonary artery. The sound is often described as a high-pitched, blowing sound that is heard best at the base of the heart.
Millwheel murmurs are often innocent and do not require treatment, but they can sometimes be a sign of a more serious heart condition. If you have been diagnosed with a millwheel murmur, it is important to follow up with your healthcare provider to determine the cause of the murmur and to receive appropriate treatment.
