Heart Sounds

by Carlo Raj, MD

Heart sounds occur via vibrations of the heart chambers secondary to the blood flowing through them. Not much vibration arises from laminar flow, but the sounds get louder when turbulence ensues. Turbulence of the blood operates on the same principles as turbulence of any fluid; variables like density, velocity, valvular diameter, and viscosity all determine the magnitude of turbulence. Listening to heart sounds via a stethoscope is called auscultation, and this part of the physical examination is an extremely valuable first-line diagnostic step. With many years of auscultation experience, a physician can identify sounds that correlate with pathologic lesions in the heart.

Love the way he teaches. Great sense of humor and very keen on review and incorporation of physiology.

so clear.
