Abstract

We validated a symbolic approach to assess autonomic modulation from pulse interval (PI) and systolic arterial pressure (SAP) series obtained from an animal model of chronic heart failure (CHF). We studied three groups of rats: controls; CHF animals; CHF animals treated with spironolactone (CHF-SP), reducing sympathetic activity in CHF. Simulations confirmed that symbolic analysis captures modifications of cardiovascular regulation in the case of fast dynamics and negligible variance. While spectral indexes did not reveal any significant difference among groups, symbolic analysis pointed out that sympathetic modulation is reduced in CHF group and restored to basal values in CHF-SP one.
