Through 1 year, measures of pacing threshold, impedance, R-wave amplitude, percentage pacing, and battery voltage remained similar to those seen in the initial 3 months of follow-up, according to Vivek Reddy, MD, of the Icahn School of Medicine at Mount Sinai in New York City.
Also, there were no additional adverse events uncovered from 3 to 12 months in the 33 patients enrolled in the preliminary study, Reddy reported at the Heart Rhythm Society meeting here.
The results indicate that leadless right ventricular pacing is feasible, Reddy said. He acknowledged that the study was small, but said that "this raises the possibility of being able to remove the weakest link of pacemaker systems, which is of course the lead."
