Heart Rate Variability Analysis of Normal Sinus Rhythm, Atrial Fibrillation and Supraventricular Arrhythmia Using ApEn, HRV Index and LFHF Ratio
نویسندگان
چکیده
Heart rate variability (HRV) is the result of variation in time between two successive heart beats. HRV is the tool for investigation of healthy and diseased condition. It also reflects an influence of autonomic nervous system on function of heart. In this study, our aim is to distinguish normal sinus rhythm from atrial fibrillation and Supraventricular arrhythmia. Here the ECG signal is pre-processed and R-peak detection is done using Coiflet2 wavelet. HRV analysis is done by three statistical parameters such as ApEn, HRV triangular index and LF/HF ratio. The ratio between low and high frequency components (LF/HF ratio) of HRV spectra represents a measure of sympatho-vagal balance. But this parameter shows better results for short term recordings hence another parameters ApEn and HRV triangular index are considered to analyze HRV analysis for both long term and short term recordings.

INTRODUCTION AND BACKGROUND: BENEFITS OF SELF-MEASURE Self-Measure (SM) of heart rate variability (HRV) may provide a novel tool to monitor and to manage atrial arrhythmias. In the present article, I report my experience monitoring HRV and arrhythmias simultaneously, and how I discovered that acute episodes of high intensity interval exercise (HIIE) terminated atrial arrhythmias. I propose that...
