Background: The problem Pulse Rate Variability (PRV) in type 2 diabetes and increased body mass index has not been studied enough. Type 2 diabetes affects the peripheral vasculature leading to coronary, cerebral and peripheral vascular disease associated with oxidative stress and inflammatory processes. Similarly increased body weight also changes oxidative stress and inflammation that may adversely affect diabetes disease progression.
Methods: The Heart Rhythm Scanner Special Edition Version 1 (Biocom Technologies, USA) was used for PPG (Photoplethysmography) recording and PRV analysis.
Results: Our study found that short-term measurement of PRY shows some statistically significant differences using multifactorial analysis of type 2 diabetes with overweight and a healthy control group with normal weight. Short- term measurements of PRV can be used as an alternative method for HRV. PPG-method can be used as preliminary screening tool for large populations with increased risk of heart problems. This is because the PPG method is simple to use and takes much less time.
