KARDIA: A Matlab software for the analysis of cardiac interbeat intervals

Ectopic beats detection and correction methods: A review

“…Moreover, some of the previous algorithms were used in non commercial heart rate variability software tools [95][96][97][98][99][100].…”

Psychophysiological correlates of chronic worry: Cued versus non-cued fear reaction

“…The cardiac defense pattern is indicated by the presence of a significant cubic trend (Graham and Slaby, 1973): from first acceleration to first deceleration, from first deceleration to second acceleration and from second acceleration to second deceleration. Matlab software Ecglab (Carvalho et al, 2002) and KARDIA (Perakakis et al, 2008) were used for R peak detection and R interval analysis, respectively.…”

Robust heart rate variability analysis by generalized entropy minimization

“…For example, currently available R and MATLAB statistical software packages for HRV analysis mostly deal with outliers by allowing the user to manipulate directly the HRV records (Perakakis et al, 2010;Rodríguez-Liñares et al, 2011). This kind of pre-processing, however, comes with a major risk: the filtered trajectory might be clear of evident outliers, but other atypical observations incompatible with the assumed model remain hidden within the processed sample.…”
