Recurrent pulseless electrical activity and cardiac arrest caused by baroreceptor failure following neck irradiation

Baroreceptor damage and hypersensitivity can produce labile autonomic blood pressure control. Neck irradiation for malignancy is a well-known but under-recognised cause of baroreceptor failure. We describe a dramatic delayed complication of neck irradiation treatment. Our patient developed recurrent unexplained hypotension and pulseless electrical activity cardiac arrest upon connection to intermittent haemodialysis, which he had previously...
