In cells, structures called Golgi Bodies (also known as Golgi apparatus or Golgi complex) are stacks of membrane-covered sacs that package and move proteins to the outside of the cell.
Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats.
In the intensive care setting, where the arterial waveform is available, pulsus paradoxus can be diagnosed by visualising changes in the systolic blood pressure tracing during the inspiratory and expiratory phases of respiration.
