WebOct 18, 2024 · The higher the sensing value, the lower the sensitivity to detect the intrinsic electrical signal. Thus, a setting of 8 mV requires at least an 8 mV electrical signal for the pacemaker to detect. A 2 mV setting will allow any signal above 2 mV to be sensed by the pacemaker. Figure 6. Concept of sensitivity. WebJan 17, 2024 · The programmed sensitivity is the smallest signal that will be detected as a cardiac event; thus, a setting of 0.5 mV is twice as sensitive as 1.0 mV. In general, a sensing safety margin of 2 is preferred (sensitivity set to 0.5 mV if atrial electrogram is 1.0 mV). Sensitivity is adjusted to improve oversensing or undersensing.
