Attention: In the 4396 clinical study, 14 of 106 subjects (13.2%) had pacing capture thresholds (PCT) ≥ 3.0 V (measured at 0.5 ms at 3 months). PCT ≥ 3.0 V can be associated with phrenic nerve stimulation, battery depletion, and loss of capture. The Model 4396 lead provides a straight tip, tined fixation, and small diameter, which may be needed for some patients. See the technical manual for more information.
