Permanent pacemakers are intelligeht devices that are indicated for the treatment of slow heart rhythms that frequently lead to dizziness or passing out (syncope).  Pacemakers are generally inserted under the skin on the chest wall just below the collarbone.  The pacing wires are threaded through the large vein under the collarbone into the chambers of the heart using fluorscopy.  A small incision is then made in the skin, and a pocket is created to house the pacer and wires.  The pocket is usually closed with absorbable sutures under the skin.  You will stay in the hospital overnight, and the incision is usually well healed within 7-10 days. Once the incision is healed, you may return to full activity, usually with no restrictins.  Today's pacemaker batteries often last for 10 years or longer.
