There are many types of pacemaker with some helping assist the sinus node by pacing the heart’s top chambers...
Micra and Micra AV
Medtronic currently makes the only FDA approved leadless pacemakers (Micra and Micra AV). The Medtronic leadless pacemaker is implanted through the femoral vein. A small hole is made in the femoral vein (near the
groin) and a catheter (a thin tube) is advanced to the heart. Through this thin tube, the leadless pacemaker is placed in the ventricle and held in place by tines (thin wires) that embed into the heart muscle. The pacemaker is then checked using a wireless bluetooth connection and the tube is removed. There is no incision on the chest to place the pacemaker. As there are no wires and no chest incision, there are no arm activity restrictions. The main restriction is no heavy lifting for one week before resuming all usual activities.
