Poincaré plot analysis of ECG uncovers beneficial effects of omaveloxolone in a mouse model of Friedreich’s ataxia

Poincaré plot analysis of ECG uncovers beneficial effects of omaveloxolone in a mouse model of Friedreich’s ataxia, Figueroa, Francisco et al., Heart Rhythm, Volume 0, Issue 0. DOI: 10.1016/j.hrthm.2024.12.041

Our study revealed significant electrical propagation disturbances and sexual dimorphism in FXN-cKO mice with severe cardiomyopathy. Poincaré plots identified irregularities in heart rhythm and ANS dysfunction. OMAV improved heart function by stabilizing early repolarization and reducing disparate arrhythmias. This work stresses sex-specific ECG interpretations and alternative mathematical approaches for drug testing in FA models.
