Impedance trends from St Jude Medical Merlin remote monitoring for the 3 patients show variation in the pattern of sporadic high impedances. A: Composite impedance trend over the first 2 years for patient 1. Multiple high impedances are seen. B: A single high impedance value was seen in patient 2, a few months after he had been programmed to a mode that avoided ventricular pacing. A few moderately high impedances were also seen in this patient. C: Patient 3 had a single high impedance value occurring 27 months after implant.
