6 Questions
What is the primary reason for the difference in time between S1 and S2 compared to the time between S2 and the next S1?
The variation in valve closure timing between mitral/tricuspid and aortic/pulmonic valves
In which region of the chest wall is the second heart sound typically heard?
The second right and left intercostal spaces
During which phase of the cardiac cycle does the pulmonic valve close?
Ventricular relaxation (diastole)
What is the normal pattern of S2 in younger patients?
A split sound with aortic closure followed by pulmonic closure
Why is S1 not split?
Because the mitral and tricuspid valves close at slightly different times
What is the characteristic rhythm produced by the presence of extra heart sounds S3 and S4?
A gallop rhythm
Test your knowledge on cardiac examination, focusing on auscultation using a stethoscope diaphragm and the identification of S1 and S2 heart sounds. Learn about the mitral, tricuspid, aortic, and pulmonic valve regions and their roles in systole and ventricular contraction.
