Quantification of heart rate variability for health analysis

摘要

The estimation of heart rate variability (HRV) has become an increasingly popular and important tool for studying many disease pathologies in the past twenty years. This paper shows a Matlab software named KARDIA that is used for the analysis of cardiac interbeat interval (IBI). The graphic user interface of this Matlab software, KARDIA helps us to allow the study of phasic cardiac responses (PCRs) and also helps in the estimation of time and frequency domain HRV parameters. Detrended fluctuation analysis (DFA) method determines the scaling exponent of the heartbeat which are always fluctuating. The results like Grand average and individual subject outcome can be transferred to spreadsheets for further study purpose. The Matlab Software, KARDIA is available free of charge with the help of GNU public license, this will help the users to change or modify their algorithm accordingly. HRVAS is also a Matlab software which are mainly used for HRV techniques for the analysis of time-domain, frequency domain analysis, nonlinear analysis, and time-frequency analysis. HRVAS provides a useful tool for HRV analysis to researchers.
