Overview

The dysautonomia seen in Guillian Barre syndrome may lead to some conduction and rhythm disturbances. Features of GBS on EKG can be 2nd or 3rd degree conduction block, QRS prolongation and T wave abnormality. However, the EKG changes are non-specific and they act as supportive not definitive diagnostic tools.

Electrocardiogram

• Findings on an ECG suggestive of Guillain Barre syndrome include:
  • ST segment depresion
  • T wave inversion
  • OT prolongation
  • Tachycardia
