Insertion of Transvenous Pacemaker.
A pacemaker wire is placed into a vein (internal jugular vein , subclavian or femoral veins) under sterile conditions, and then passed into the right atrium then right ventricle.
The pacing wire is then connected to an external pacemaker outside the body.
Transvenous pacing is often used as a bridge to permanent pacemaker placement. It can be kept in place until a permanent pacemaker is implanted or until there is no longer a need for a pacemaker and then it is removed.
Transvenous pacing usually done under imaging for proper positioning of the electrodes.
