20, upper panel). [42] Further, patients with low-amplitude R waves may require lower minimum sensing thresholds to ensure reliable sensing of VF. T-wave oversensing in the setting of a low ...
[16] More sensitive settings may be selected if the R-wave is ≤3 mV. Less sensitive settings decrease the risk of T-wave oversensing in Medtronic ICD, but may increase the risk of undersensing VF.
