Key result
Lower spinal canal subarachnoid hemorrhage can produce marked morphological electrocardiogram changes similar to those seen in intracranial subarachnoid hemorrhage.
EKG changes typically associated with intracranial subarachnoid hemorrhage can also occur when the bleeding originates in the lower spinal canal.
Answers are grounded in this paper and cite their sources.
Clinicians should consider spinal SAH in unexplained neurogenic ECG changes; single case leaves association hypothesis-generating pending confirmation.
Marked morphological electrocardiographical changes occurred in a patient whose subarachnoid hemorrhage originated in the lower spinal canal. Thus, the electrocardiogram can show the changes well known for intracranial subarachnoid hemorrhage even when the source of bleeding is in the lower spinal canal.
