. Pacemaker Implantation

What is it 

A pacemaker is a battery-powered device placed under the skin or the muscle (usually on the anterior chest) connected to different heart chambers with leads (cables). An electrical impulse sent through the leads will cause the heart to beat whenever is needed. Single chamber pacemakers have one lead, dual chamber pacemakers have two, and biventricular pacemakers have three leads (Fig 1). In addition, the Micra® and Nanostim® single chamber pacemaker have only recently become available and are made of a capsule slightly bigger than the size of the coin (Fig. 2). The capsule contains the whole pacemaker “head” and battery, is implanted from the femoral vein (a large vein in the groin) into the right ventricle (the chamber that pumps blood into the lung), and does not require surgical incision of the chest or placement of any leads in the heart (Fig. 2). Patients are usually discharged 2 days after the operation.




What we perform

We offer all the different current technologies in pace-maker implants including, single, double, biventricular and leadless pacemakers. Devices compatible with magnetic resonance imaging can be implanted if necessary. The type of pacemaker will be decided according to your heart’s electrical and mechanical condition.

Why a patient needs a pacemaker

The heart is a pump controlled by electrical signals. If the sino-atrial (the main pacer of the heart) or the atrio-ventricular node (which transmits electrical impulse from the collecting to the pumping heart chambers) are not functioning properly, a profound bradycardia (slow heart beat) can occur, resulting in shortness of breath, inability to exercise and fainting. Further deterioration up to a complete absence of any cardiac beat can happen. Biventricular pacemakers, where leads are implanted in the right and left ventricle (the 2 pumping chamber of the heart) are implanted in selected patients with heart failure, to support and improve heart functioning.
