    Strictly speaking, ECG data are neither "chaotic" nor "stochastic".
    ECG data are complex real-world data.

    The terms "chaotic" and "stochastic" relate to models - human made constructs.
    "Chaotic" usually means the system exhibits deterministic chaos.
    "Stochastic" usually means there is some non-deterministic step allowed.

    As there are no perfect models for ECG data
    we may conclude that ECG data are more "stochastic" than "chaotic".
