Cardiac pacemaker in high spinal cord injury.

Area of Science:

• Neurology
• Cardiology
• Autonomic Nervous System

Background:

• Acute cervical spinal cord injury can cause autonomic nervous system imbalance, leading to bradycardia and cardiac arrest.
• This is often attributed to the dissociation of parasympathetic and sympathetic responses during spinal shock.

Observation:

• A patient with C2 complete quadriplegia from birth trauma experienced persistent, symptomatic bradycardia for 21 months post-injury.
• Standard medical management did not resolve the bradycardia.

Findings:

• Cardiac pacemaker implantation led to significant clinical improvement in the patient.
• This suggests a potential long-term solution for bradycardia unresponsive to medical therapy.

Implications:

• Cardiac pacing may be a viable treatment for persistent, symptomatic bradycardia in patients with high cervical spinal cord injuries.
• Further investigation into the etiologies of prolonged bradycardia post-spinal shock is warranted.
