The brand new pacemaker, referred to as the Micra Transcatheter Pacing System, is simply an inch lengthy, about one-tenth the dimensions of conventional units, and is the primary "leadless" pacemaker to be accepted to be used in america.
Pacemakers are surgically implanted units that generate electrical impulses to deal with irregular or stalled heartbeats. Typical pacemakers are positioned beneath the pores and skin close to the collarbone and related to the guts by lead wires that run via a vein.
