[Mechanical human heart work in a newborn infant].
The echo- and dopplerography of newborn infants up to 10-day age revealed that their heart work capacity was about 6 Wt, relative capacity--25 Wt/100 g of ventricular mass. These data correspond to those of adult humans. The Frank-Starling mechanism was corroborated.
