1/f fluctuations in heart rate are usually measured by spectral analysis using Fast Fourier Transform. Here, we introduce a new method based on counting the number of QRS complexes in time intervals At of various length. For a l/J\* spectrum the variance of counts in A t follows a power-law as A t 1
