Key Result

12-lead ECG recordings in a patient with Brugada syndrome demonstrated progressive RS-T segment and J wave elevation immediately preceding and following an episode of ventricular fibrillation.

Key Points

  • To analyze the dynamic changes in 12-lead ECGs before and after ventricular fibrillation in a patient with Brugada syndrome.
  • Recorded 12-lead ECGs before and after an episode of ventricular fibrillation.
  • Documented RS-T segment and J wave changes in relation to R-R intervals during atrial fibrillation.
  • Notable progressive elevation of RS-T segments and J waves before and after VF.
  • Established a close relationship between RS-T segment amplitude and R-R intervals during atrial fibrillation.

Dynamic ECG changes in a Brugada syndrome patient support the hypothesis that RS-T elevation and subsequent VF are related to a transient outward current-mediated spike-and-dome morphology.

Abstract

We present a patient with Brugada syndrome in whom 12-lead ECGs were recorded just before and after an episode of ventricular fibrillation (VF). A progressive elevation of both the RS-T segment and J waves just preceding and following the VF, and a close relationship between the amplitude of the RS-T segment and the preceding R-R intervals during atrial fibrillation, were documented. These findings support the hypothesis that RS-T elevation and a subsequent VF are related to a transient outward current-mediated spike-and-dome morphology of the epicardial action potential.

Matsuo et al. (1998) conducted a case report in Brugada syndrome (n=1). 12-lead ECG was evaluated on Dynamic changes of RS-T segment and J waves. 12-lead ECG recordings in a patient with Brugada syndrome demonstrated progressive RS-T segment and J wave elevation immediately preceding and following an episode of ventricular fibrillation.
