RT Journal Article SR Electronic A1 Vinall, Maria T1 Miniature Leadless TPS Shows Favorable Electrical Performance JF MD Conference Express YR 2015 FD SAGE Publications VO 15 IS 22 SP 10 OP 10 DO 10.1177/1559897715598280 UL http://mdc.sagepub.com/content/15/22/10.abstract AB In the Micra Transcatheter Pacing Study, a novel leadless pacemaker system delivered using a transcatheter system, was tested for strength duration and battery longevity. Despite its size, the electrical performance of the device was comparable with current ventricular demand pacemakers and utilization of 0.24 vs 0.4 milliseconds pulse width increased the projected battery longevity by 0.83 years.
