Pacemaker/Defibrillators

Pacemaker/Defibrillators at Palm Beach Cardiology Center

A pacemaker is implanted to treat bradycardia (an abnormally slow heart rate). Pacemakers can also adjust the heart rate to meet the body’s needs, whether during exercise or rest. Implantation of a pacemaker involves positioning leads (thin, insulated wires) in the heart and placing the device in a pocket of skin, usually in the shoulder area. Typically the implant procedure involves only local anesthetics and a sedative, rather than general anesthesia.

An ICD (implantable cardioverter defibrillator), or defibrillator, helps stop dangerously fast heart rhythms in the ventricles (the heart’s lower chambers). The device is used to treat sudden cardiac arrest and to restore a normal heartbeat. Implantation of a defibrillator involves positioning leads (thin, insulated wires) in the heart and placing the device beneath the skin, usually in the shoulder area. Typically the implant procedure involves only local anesthetics and a sedative, rather than general anesthesia. Most people have a fairly quick recovery after these procedures.

Pacemaker/Defibrillators Q & A

What is a pacemaker?

A pacemaker is a small medical device implanted in the chest to help regulate the heart’s rhythm. It uses electrical impulses to maintain a regular heartbeat in patients with bradycardia (slow heart rate) or other arrhythmias.

What is a defibrillator?

A defibrillator, often referred to as an implantable cardioverter-defibrillator (ICD), is a device implanted in the chest to monitor and correct life-threatening arrhythmias. It can deliver electric shocks to restore a normal heart rhythm in case of severe arrhythmias or sudden cardiac arrest.

Why might I need a pacemaker?

You may need a pacemaker if you have a slow or irregular heart rate that causes symptoms such as dizziness, fatigue, or fainting. It helps ensure that your heart beats at a proper rate and maintains an adequate blood flow.

Why might I need a defibrillator?

A defibrillator is recommended if you are at high risk of sudden cardiac arrest due to severe arrhythmias or underlying heart conditions. It helps prevent life-threatening arrhythmias and can provide a lifesaving shock to restore a normal heart rhythm.
