Background: The aim of this study was to investigate the effects of carbon-dioxide treatment on heart rate variability (HRV) parameters: mean RR interval (RRI), standard deviation of RR intervals (SDNN), root mean square of successive RR differences (RMSSD); and Porta and Guzik indices, as measures of heart rate asymmetry.
Materials And Methods: Twenty patients were enrolled (mean±SD, age=59±7.8 years).
Aim: To study the effect of carbon dioxide (CO) therapy on the nitric oxide (NO) pathway by monitoring plasma asymmetric dimethylarginine (ADMA) concentrations.
Patients And Methods: Forty-seven hypertensive patients who underwent transcutaneous CO therapy were enrolled. Thirty healthy individuals were recruited for the control group.
