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.
When the pacemaker does not detect a heartbeat within a normal beat-to-beat time period, it will stimulate the ventricle of the heart with a short low voltage pulse. This sensing and stimulating activity continues on a beat by beat basis.n the first half of the tracing, pacemaker stimuli at 60 beats per minute result in a wide QRS complex with a right bundle branch block pattern. Progressively weaker pacing stimuli are administered, which results in asystole in the second half of the tracing.
