Heart rate is a vital sign, whereas heart rate variability is an important quantitative measure of cardiovascular regulation by the autonomic nervous system. Although the design of algorithms to compute heart rate and assess heart rate variability is an active area of research, none of the approache...

Microwave radiation and heart-beat rate of rabbits. Each of three adult New Zealand rabbits, 2 male and 1 female albinos, was exposed dorsally or ventrally, to 2450-MHz plane waves for 20 min under each of several field conditions: 1) to continuous waves (CW) at 5 mW/cm2; 2) to ...

55. Due to a higher rate of proliferation and myocardial differentiation of mesenchymal cells in the dorsal mesocardium56,57, and their subsequent insertion into the venous and arterial poles of the heart33,52,58,59, the length of the limbs of the cardiac loop increases between the left ...
About 66–72% of human mothers cradle their infants on their left side. Given that left-cradling exposes the baby’s face to the mother’s left visual field (i.e., mainly projected to her right hemisphere) and is altered by emotional states such as stres
What is the pulse rate of a normal resting person? If your blood volume is 5 L, and each beat of your heart pushes out 70 mL of blood and your heart rate of 70 beats per minute, how long does it take for all of your blood to move through your heart?
Beyond visual inspection, some work has been done on thermal imaging1,2, facial recognition3 and even using Doppler Radar4 to monitor heartbeat. However, the avenues for such monitoring are restricted by what can be emitted via human skin. Recently, Radiometry experiments on human subjects has ...
