Basically, yes. A traditional dual chamber pacemaker has 2 leads instead
of 3, but the procedure is generally the same. However, there are now
leadless pacemakers. From what I understand, they are currently only
single chamber units. They are surgically inserted, using a catheter, into
the heart via a blood vessel, most often in the groin. But they are also
attached to the interior of the heart to avoid migration. However, since
there are not any leads to contend with, there is nothing to stitch to any
chest muscle.
What I have is a pacemaker, one designed for people diagnosed with heart
failure. Mine comes with a defibrillator because I am at risk of
experiencing sudden cardiac arrest.
