     The severity of damage to the aircraft in combat was responsible for more preejection injuries, unconsciousness, and allowed less time to prepare for ejection.

   • 1995, Robert M. Bradley, Essentials of oral physiology, page 231:

     Events in vomiting are usually divided into preejection, ejection, and postejection phases (Fig. 11-1 3). The preejection phase is characterized by licking, salivation, pallor, and changes in visceral function such as tachycardia and the relaxation of the proximal stomach.

     The preejection shortening and relengthening correspond to septal beaking and flash.

preejection (plural preejections)

1. The time period immediately preceding ejection.
   • 1974, Critical Reviews in Bioengineering - Volume 2, page 156:

     We have therefore used the R-S₂ interval assuming that any prolongation that may occur is most likely a result of lengthening of R-S₁ (including preejection) rather than S₁-S₂ .

   • 2008, T. Jeff Chandler, Lee E. Brown, Conditioning for Strength and Human Performance, →ISBN, page 22:

     During systole, two main phases occur: preejection and ejection.

   • 2012, Catherine M. Otto, The Practice of Clinical Echocardiography, →ISBN, page 191:

     This is seen as abnormal rapid leftward motion of the septum during preejection followed by rightward (paradoxical) motion.
