Class Information
Number: 607/28
Name: Surgery: light, thermal, and electrical application > Light, thermal, and electrical application > Electrical therapeutic systems > Heart rate regulating (e.g., pacing) > Testing or monitoring pacer function > Measuring pacing, threshold, capture margin, or contact impedance
Description: Subject matter for determining the minimum, pulse amplitude necessary to sustain pacing of the heart, how much reserve or margin of amplitude exists above a threshold, or a load or contact impedance at the applicator interface with the body tissue as a measure of pacing efficiency.
