The main motivation for the research was the possibility of identifying changes in the degree of arousal in students during the teaching process using smart wristbands, the physiological function of heart rate as identifiers, the student’s level of arousal and the student’s partial and final lear...
The proportion of healthy subjects >65 years old for whom values extended below cutpoints was 25% for SDNN index, 12% for rMSSD and 14% for pNN50. Table 2. Aging Effects on 24-h Heart Rate Variability and Heart Rate by Decade Age (yr)SDNN (ms)SDANN (ms)SDNN Index (ms)rMSSD (ms...
The goal of atrial fibrillation treatment is to restore your normal heart rate and rhythm and prevent blood clots. Your treatment may include medications, electrical cardioversion, a pacemaker or surgery. Reply to: What is a Heart Attack? " Patrick a 70-year-old diabetic man with a 2-year...

The rate of decline in VO2peak accelerates in older age from 3%-6% per decade in the 20s to 30s to >20% per decade after the age of 70 years (16). Age-related declines in strength and balance exacerbate decrements in VO2peak caused by alterations in skeletal muscle, including atrophy...
They were categorized according to their baseline heart rate and were followed up for a mean of 47±16 months (range: 7–71 months). Over the 5-year period, 619 individuals (9.9%) developed metabolic syndrome. Men with elevated baseline heart rates were more likely to experience metabolic ...
An ECG was recorded for 500 beats for measurement of heart rate variability (HRV) and then infants were tilted to an angle of 60° (head-up). The harness held them in the pram. The foot of the pram was modified to take support at a 60° angle to the floor. The tilt took 2–3 ...
