Tuvastuslävi on elektrilise signaali minimaalne amplituud mõõdetuna mV, mille seade, nt südamestimulaator, peab tuvastama, et südametegevust täpselt registreerida.
Sensitivity can depend on the value of the quantity being measured. The change considered in a value of a quantity being measured must be large compared with the resolution.
A sensing threshold is the minimum amplitude of an electrical signal (measured in mV) that a device, such as a pacemaker, must detect to accurately register cardiac activity.
