Implication

Surface ECG may localize VT exit in right ventricular dysplasia; hypothesis-generating for ablation targeting, needs validation.

Key Points

  • Characterize the electrocardiographic presentation and anatomical pathway of ventricular tachycardia in right ventricular dysplasia.
  • Analyzed surface 12-lead electrocardiogram (ECG) tracings recorded during an active episode of sustained ventricular tachycardia.
  • ECG tracings demonstrated a left bundle-branch block configuration of the QRS complex along with left axis deviation.
  • The observed electrocardiographic pattern indicates that the reentrant circuit exits at the right inferolateral aspect of the tricuspid annulus.

Outcome
ECG characteristics of ventricular tachycardia

In right ventricular dysplasia, ventricular tachycardia can present with a left bundle-branch configuration and left axis deviation, indicating a right inferolateral exit of the reentrant circuit.
