Heart murmur

Introduction

Cause

Classification of causes:

Eight, tricuspid systolic murmur

Nine, tricuspid valve diastolic murmur

mechanism:

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).

(3) Noise properties

(four) the transmission of noise

(6) Noise classification - 1

(7) Noise classification - 2

Two-stage murmur

Effects of position, breathing, exercise, and medication on murmurs

Fourth, other cardiac signs

Five, equipment inspection
