The inability to detect Korotkoff sounds in infants have in the past made it difficult for most pediatricians to measure blood pressures by indirect conventional sphygmomanometry. Now, however, Korotkoff sounds, or the mechanical events which produce them, can be sensed with an ultrasonic Doppler device. The author measured systolic and diastolic blood pressure using a Doppler arteriokinetog raphic instrument during 6...
