This method for analyzing the cardiac activity of a patient are comprises the steps for acquiring (20) at least one cardiac said electric signal comprising at least one elementary signal corresponding to a heart beat, for extracting (29) from said elementary signal, at least one elementary wave, the general shape of which may be expressed by x(t)=x0+x1 cos(Φ(t)), wherein Φ(t) is the phase of said elementary wave, and for analyzing (30) said elementary wave, comprising the steps for determining an expression of a phase equation F ⁡ ( Φ ) = ⅆ Φ ⅆ t of said elementary wave and determining an expression of the phase Φ(t) of said elementary wave as a functions of parameters measuring the anharmonicity of said elementary wave and its morphology, from p cosn and p sinn functions defined by: p ⁢ ⁢ cos n ⁡ ( t , r ) = ∑ k = 1 ∞ ⁢ cos ⁡ ( kt ) ⁢ r k k n ⁢ ⁢ and ⁢ ⁢ p ⁢ ⁢ sin n ⁡ ( t , r ) = ∑ k = 1 ∞ ⁢ sin ⁡ ( kt ) ⁢ r k k n .
