The role of ischemic neurodegeneration of the nodose ganglia on cardiac arrest after subarachnoid hemorrhage: An experimental study

► If neurons of the nodose ganglia are lesioned due to ischemic insult during subarachnoid hemorrhage, heart rhythm regulation by vagus afferent reflexes is disturbed. ► The new management strategies for minimizing cardiac arrest within the first few hours of the initial SAH are required to effectively alter the clinical course of this disease. ► The cause, ultimate clinical importance and treatment of the brain-heart connection in pathological states, remains to be elucidated.
