Study note

Leadless pacemakers and non-transvenous defibrillators

THE CONTEXT

These implantable devices have alternative arrangements associated with a lower likelihood of infection.

•

Leadless pacemakers are very small devices implanted into the trabeculated right ventricular septum.

•

They are considerably less likely to become infected and provide ventricular pacing only.

•

Defibrillation leads are placed above or underneath the sternum, with the generator outside the sternum.

•

These devices have no intravascular components, making infection and resulting bacteraemia less likely.
