Web19 de dez. de 2024 · Defibrillation impedance (also termed shock or HV impedance) can be measured in two different ways: either through a high output therapy—termed true shock impedance (TSI); or through a calculated value derived using a low voltage sub-threshold measurement (LVSM). 2–4 True shock impedance is rarely performed as a routine test … In analog circuits a high impedance node is one that does not have any low impedance paths to any other nodes in the frequency range being considered. Since the terms low and high depend on context to some extent, it is possible in principle for some high impedance nodes to be described as low impedance in one context, and high impedance in another; so the node (perhaps a signal source or amplifier input) has relatively low currents for the voltages involved.
