Temporary pacing electrodes are passed transvenously to the heart for stimulation therapy, into the right atrium or ventricle and connected to an external temporary pacemaker. Floating stimulation electrodes (balloon catheters) do not require an X-ray control for this.
Transvenous stimulation electrodes are used for emergency stimulation or for peri-operative use. Special applications are, for example, rapid pacing during TAVI procedures.
