Descriptive ethics will hence try to oversee whether ethics still holds its place. Because descriptive ethics involves empirical investigation, it is a field that is usually investigated by those working in the fields of evolutionary biology, psychology, sociology or anthropology. Information that comes from descriptive ethics is, however, also used in philosophical arguments.
To deactivate an ICD or alter pacemaker function, a magnet has to have a field strength of 10 gauss (a unit of magnetic strength) or greater next to the surface of the device. A magnet in a stereo speaker has a field strength of 100 gauss at the surface - but 0 gauss 6 inches away.
No p-wave occurs so the pacer fires the atrial pacing wire causing a pacer spike on the EKG. The pacer then waits the programmed amount of time to see a QRS. If no QRS occurs the ventricular pacing wire is activated and a paced QRS occurs. At any point in the process the heart can kick in with it own beat and inhibit the pacer. It sounds like in this person the pacer is firing for the SA node and his own rythmn responds and carries through with the rest of the beat.
