What makes the S1 heart sound? | MITRAL & TRICUSPID valve closure. Systolic murmur occurs before S2 begins. |
What makes the S2 heart sound? | AORTIC & PULMONARY valve closure. Diastolic murmur occurs before S1 begins again. |
What makes an S3 heart sound? | Occurs at the end of rapid ventricular filling. Called a proto-diastolic gallop. “Sloshing in” blood rushing into non- compliant ventricular wall (Tennessee). Assoc/w dilated CHF. NORMAL IN CHILDREN & YOUNG ADULTS. |
What makes an S4 heart sound? | High atrial pressure/stiff ventricle. Presystolic gallop. “A stiff wall” blood being forced into a stiff/hypertrophic ventricle. (“Atrial kick”) is assoc/w a hypertrophic ventricle. SOMETIMES audible in healthy children. |
What does a wide pulse pressure indicate? | Systolic is the force of the pumping, diastolic is the resistance. WPP means heart is pumping hard against little resistence (vasodilation or low blood volume). Means it’s difficult to move blood (sludge). |
