Popis: Haemodialysis (HD) patients who undergo long-term treatment are very susceptible to arterial stenosis. In this study, we propose two main features taken from patients undergoing the dialysis process, namely: Rising Slope – RS and Falling Slope - FS. These features are yielded from a photoplethysmography signal extraction on the hand that is used to create vascular access called HD hand. Eleven dialysis patients with the arteriovenous fistula (AVF) method were the object of this study. The feature data was taken twice, before and after the dialysis process. Utilizing the t-test on the variance of RS features on the HD hand showed a statistically significant value of 0.0211 (p
