Heart Rate Variability (HRV) analysis is a vital tool in assessing autonomic nervous system regulation and cardiovascularhealth. This study explores improved HRV analysis techniques by employing MATLAB code and comparing its performance withwidely used software tools, Kubios and gHRV. Electrocardiogram (ECG) data from ten subjects under four distinct conditions -baseline, rest, Stroop color task, and meditation - were collected and analyzed. The study focuses on developing and implementingnovel algorithms in MATLAB for HRV estimation, providing a comprehensive comparison against existing methods. The studyexamines the accuracy and reliability of HRV analysis results obtained through MATLAB implementation in contrast to Kubiosand gHRV. The MATLAB code is optimized for enhanced computational speed and accuracy, allowing for real-time processingof ECG data. The results indicate significant improvements in HRV analysis using the proposed MATLAB implementation. Theproposed MATLAB code and Kubios have similar accuracy for the High-Frequency feature, with 85% accuracy. gHRV, on theother hand, has 100% accuracy for PNN50, indicating its high accuracy in matching reference data. The comparative analysisdemonstrates the diverse HRV metrics across different experimental conditions. Additionally, the results highlight the differencein the study approach between Kubios and gHRV, showcasing its potential for widespread adoption in clinical and researchsettings.This study not only presents an advanced HRV analysis methodology but also provides valuable insights into the reliability ofexisting software tools. The findings offer researchers and clinicians an informed choice when selecting HRV analysis tools fortheir specific applications, ensuring accurate and efficient assessment of cardiovascular health and autonomic nervous systemfunction. Further investigations and validations are warranted to establish the robustness and generalizability of the proposedmethodology across diverse populations and experimental paradigms
