Recurrent syncope secondary to autonomic dysfunction in spinal cord injury: a case report.

High-level spinal cord injuries are often associated with autonomic impairment, which can result in orthostatic hypotension and syncope. Persistent autonomic dysfunction can manifest with disabling symptoms including recurrent syncopal events. We describe a case of autonomic failure resulting in recurrent syncopal events in a tetraplegic 66-year-old man.
