amplitude as the catheter approaches the top of the cavo-atrial junction. As the catheter advances into
the right atrium, the P-wave will decrease in amplitude and may be biphasic or invert.
Magnetic Navigation
Permanent magnets are encapsulated within the tip of the Sherlock 3CG™ TPS Stylet. No magnetic
energy is generated by the display or the sensor. The Sherlock 3CG™ TCS displays the relative position of
the magnet-tipped stylet to the sensor. It does this in two steps:
1.
Sherlock 3CG™ TCS takes a background measurement of the ambient magnetic field during the
calibration cycle.
2.
Sherlock 3CG™ TCS senses changes in the magnetic field. When the Sherlock 3CG™ TCS detects
the stylet, it displays the stylet tip location and orientation.
