We present several recent studies based on statistical physics concepts that can be used as
diagnostic tools for heart failure. We describe the scaling exponent characterizing the long-range
correlations in heartbeat time series as well as the multifractal features recently discovered in
heartbeat rhythm. It is found that both features, the long-range correlations and the multifractility,
