Three of these measurements mainly assess parasympathetic function : heart rate responses to deep breathing (beat-to-beat variation), to standing (30 15 ratio), and to the Valsalva maneuver.
After delivery, the neonates were assessed for viability (breathing, beating of the heart, pulsation of the umbilical cord or definite movements of voluntary muscles), and their APGAR scores at the first, fifth and tenth minutes were determined.
The survey used the international definition of child mortality, under which any birth in which a child showed any sign of life such as breathing, beating of the heart, or movement of voluntary muscles is defined as a live birth.
A viable fetus was considered stillborn if it did not show any evidence of life at birth such as breathing, beating of the heart, pulsation of the umbilical cord or definite movement of voluntary muscles, whether or not the umbilical cord had been cut or the placenta was attached [ 17].
During the 3 min paced breathing protocol, beat-to-beat SAP and the RR interval (RRI) time series were constructed for frequency analysis.
Finally, real time operation greatly assists with reducing motion artifacts, associated with e.g. breathing, heart beat or vascular movements, thus dynamic processes can be visualized with high temporal and spatial resolution.
It was those high-minded connoisseurs the brothers Goncourt who, in 1861, spelled out the relationship between Rembrandt's athletic treatment of the paint surface and the expression of human vitality: "Never has the human form, living and breathing and beating in the light, been conveyed by the brush as by his".
Also, eventual patient movement in addition to breathing and beating heart is not modeled.
With this additional study, we demonstrated that the heart motions (both due to breathing and beating) need to be corrected for in order for PVC to successfully take place.
This said, we acknowledge that the breathing and beating motion are a tangible and cumbersome issue when cardiac datasets are of interest and that in the current clinical practice, there is often no time nor means to perform a fully dual-gated PET reconstruction.
The piece even pulsated with light from its center; breathing and beating to the score.
