Classification of causes:
Eight, tricuspid systolic murmur
Nine, tricuspid valve diastolic murmur
mechanism:
Examine
an examination
First, the history of illness
Second, the general inspection
Third, cardiac auscultation
(1) Staging of noise
For example, the murmur is most loud at the apex of the apex, suggesting that the lesion is in the mitral valve; it is prone to ringing in the aortic valve area, suggesting that the lesion is in the aortic valve; the loudest in the pulmonary valve area, suggesting that the lesion is in the pulmonary valve; the loudest at the lower end of the sternum. However, the high-pitched descending aortic murmur of aortic regurgitation is often the most common in the 3rd and 4th intercostal spaces of the left sternal border (ie, the second auscultation area of he aorta).
