DB_Heart Rate Recovery_INER

There are several methods to assess the function of the autonomic nervous system. One method that is easy, low-cost, and acceptable by the scientific community is heart rate recovery (HRR). Different pathological conditions have been related to the development of autonomic dysfunction. The aim of our study was to evaluate the relationship between heart rate recovery (HRR) and HRR-derived parameters and respiratory, biochemical, and hematological condition in controlled patients of the medical service of the National Institute of Respiratory Diseases, Mexico City. All participants were subjected to anthropometric and respiratory evaluations. Fasting blood samples were taken before participants performed a 6-minute walking test (6MWT), and the blood analysis included chemical and hematological tests. After the 6MWT, heart rate (HR) was recorded at rest during the last 5 min. and was used to estimate HRR and relative HRR (rHRR) at the first and second minutes. Data base of nutritional, serum biochemical, blood cells counts, six-minute walking test measurement of controlled patients is present as data base reservoir of a pilot study title "Biochemical and hematological relationship with the evaluation of Autonomic Dysfunction by Heart Rate Recovery"
