RT Journal Article SR Electronic T1 Postinduction Paced Pulseless Electrical Activity in a Patient With a History of Oropharyngeal Instrumentation–Induced Reflex Circulatory Collapse JF Ochsner Journal JO Ochsner J FD O.

The patient's condition stabilized, and she underwent successful cataract extraction, intraocular lens implantation, and pars plana vitrectomy.Conclusion: Cardiac pacemaker insertion prior to performance of a procedure historically associated with reflex circulatory collapse can be expected to protect a patient from bradycardia but not necessarily hypotension.
