What is Intermittent Dynamics and 1/F^beta Noise in Single Cardiac Muscle Cells about?

Fluctuations in the spontaneous beating activity of isolated cardiac cells were studied over a timescale of six decades. The beat dynamics of single cardiac cells were heterogeneous and intermittent. The interbeat intervals (IBIs) were power-law distributed in a long-time regime. Furthermore, for long timescales up to the experimental window, the autocorrelation of IBIs exhibits a scaling behavior of 1/f^beta-noise type. These observations suggest that 1/f^beta noise is an intrinsic characteristic of spontaneous activity of single cardiac cells.
