The fundamental concept of electroanatomic mapping systems is to localize catheters within the heart in three dimensional space (a sort of "GPS" within the heart). Building a 3-D model of the heart with real-time visualization permits reduction in fluoroscopy use. In addition to 3-D structure, the voltage and timing of signals at each point of ...
Heart signals were indeed seen, but were very noisy. The next development was by David Cohen , [ 2 ] who used a magnetically shielded room to reduce the background, and a smaller coil with better electronics; the heart signals were now less noisy, allowing a magnetic map to be made, verifying the magnetic properties and source of the signal.
In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.

A karyotype is the general appearance of the complete set of chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes.
For example, the physiological arousal, heart pounding, in a response to an evoking stimulus, the sight of a bear in the kitchen. The brain then quickly scans the area, to explain the pounding, and notices the bear. Consequently, the brain interprets the pounding heart as being the result of fearing the bear. [4]
The Managed Heart: Commercialization of Human Feeling, by Arlie Russell Hochschild, was first published in 1983. [1] In it, she documents how social situations influence emotions through the experiences of flight attendants and bill collectors. A 20th Anniversary edition with a new afterword added by the author was published in 2003.
