a periodic increase in blood pressure (bp) occurs during apneic episodes in patients with obstructive sleep apnea (osa). several factors including hypoxemia and an increase in heart rate (hr) were reported to be responsible for this increased bp. to examine the contribution of these two factors in increasing bp, 35 healthy male subjects (mean age±sd= 23.64±3.80) were studied in three experiment...

objective: for many years in herbal medicine the antihypertensive and lowering blood lipid properties of achillea wilhelmsii (a. wilhelmsii) have been suggested. in the present study the impacts of the plant extract on rabbit’s blood pressure and heart rate have been investigated. materials and methods: twelve nwz rabbits weighed 2-3 kg were randomly divided into two groups of 6 rabbits. the te...

conclusions the mean heart rate was higher in participants who were overweight than those with normal weight. results the mean and standard deviation of the heart rate in the hot climatic condition and moderate exercise were 103.84 (3.34) for normal weight subjects and 108.67 (3.27) for overweight subjects. the mean and standard deviation of the heart rate in a very hot climatic condition and l...

background and objective: obstructive sleep apnea syndrome (osas) is a prevalent disease in adults. limited evidence regarding the effect of severity of sleep apnea and depression on heart rate variability (hrv) indices exists. hence, we decided to focus on the association between hrv and severity of osas based on depression score. materials and methods: a total of 193 patients with confirmed o...

in this paper the main objective is to quantify and compare the instantaneous value of heart rate for normal breathing patterns during meditation and non meditation conditions. this paper involves analysis of variance (anova) technique for the analysis of the heart rate variability patterns during the meditative and non meditative states. the analysis is divided into three stages i.e. data acqu...
