Give me the quick and easy on murmurs. What are the two main types of murmurs?
There are diastolic and systolic murmurs. Murmurs are defined by location Aortic, Pulmonic, Mitral, or Tricuspid. And they are either stenotic or regurg.
murmurs will sound harsh, and regurg
will be blowing.
- Here are some pearls on the 4 basic ones:
- Aortic stenosis will be heard best at the right sternal border, and the valve has to be open for blood to flow to your brain, making it a systolic murmur. It will radiate into the neck (the direction of the blood flow), and is harsh.
will be heard in left mid sternal border, and its blowing. The valve has to be closed, making it a diastolic murmur. It radiates along the right sternal border. It is associated with all those weird signs like De Mussets, and the water hammer pulse.
the valve is open, and it helps me to know its the opposite of aortic stenosis in that its a diastolic murmur. Its heard best at the apex, is harsh, and does not radiate. Its easiest to find in the left lateral decubitus position. There is often a loud opening snap heard.
the valve is closed, its systolic, blowing, and radiates to the left axilla (direction of flow of the blood as it bounces off the valve).
