Marie’s Cardiac exam – Part I – Rest
We just released the first part of an extensive cardiac assessment of Marie’s heart. In the first part we auscultate all important auscultation sites (aortic, pulmonic, ERB, tricuspid, mitral) at rest.
The positioning of the stethoscope head is important to clearly distinguish the different heart tones and therefore have an impression of the efficiency of the particular heart valves. As many of you know, S2 is best heart on the aortic/pulmonary area (above) and S1 is best heart on the tricuspid/mitral area (below).
Below a short extract from the auscultation video where we auscultate Marie’s ERB’s point with the diaphragm. At this particular auscultation site we are able to hear S1 and S2 sounds equally, so S1 (lub) = closure of mitral and tricuspid valves, and s2 (dub) = closure of aortic and pulmonic valves. This gives a rich and equally balanced heart tone.
Erb’s point is a combination of the aortic and pulmonic areas in terms of what you will hear. It is the place where potential heart murmurs, located at the third intercostal space and the left lower sternal border, could be located.
The splitting of the second heart tone into A2 and P2 is heard best during inspiration over Erb’s point. During expiration A2 and P2 fuse.
