                         RR intervals, the second-order difference plot provide a graphical 
                         representation of the degree of variability of time series. In 
                         total are analyzed 122 tachograms collected by Polar monitor and 
                         then classified into two groups: 61 healthy young adults and 61 
                         adults in preoperative evaluation for coronary artery bypass 
                         grafting for severe coronary disease. This approach identified the 
                         tachograms with high and low variability, which demonstrates the 
                         ability of second-order difference plot to discriminates both
