What is the heart murmur memory formula?

Heart murmur memory formula is generally two or three valve closed like blowing, two or three stenosis rumbling, aortic valve closed in sigh, arterial duct like machine, myocarditis such as music.1. Two or three valve closed like blowing refers to the heart murmur when the mitral valve and tricuspid valve are closed, which may produce similar blowing sound or blowing sound, usually related to the abnormal function of mitral valve and tricuspid valve. 2. Two or three stenoses Rumble refers to heart murmurs when the mitral and tricuspid valves are narrowed.
