Systolic Murmurs and Innocent Murmurs
1991Cardiac murmurs are produced by turbulent blood flow. Turbulence is determined by the Reynolds number, which is the ratio of inertial to viscous forces in a fluid. The Reynolds number (NR) may be determined from the following formula: NR = (σ/η) \(bar V\)D where σ is the fluid density in gm/ml, η = fluid viscosity (poise), \(bar V\) = average velocity ...

There was a time, not so very long ago, when on hearing a systolic murmur over the heart, even in the absence of any other important abnormalities, the physician would pronounce the ominous verdict that the patient ...
