Electrophysiology Study

Our Electrophysiology Laboratory is equipped with the most recent technology to help physicians and staff diagnose and treat irregular heart rhythms, known as arrhythmias. Specific treatments that are available through the electrophysiology lab include:

Implantable defibrillators - Surgically implanted in the chest, this battery operated device monitors and corrects abnormal heart rhythms by sending electrical charges to the heart.

Pacemakers - a device implanted into a patient's chest to send electrical signals to the heart, telling it when to beat. It is used to correct a form of abnormal heart rhythm (arrhythmia) in which the heart beats too slowly.

Catheter ablation - a procedure to restore normal rhythm by destroying very small, carefully selected parts of the heart that cause tachycardia.

Who gets arrhythmias?

Arrhythmias are usually a byproduct of damage to the heart from disease or age. People with otherwise healthy hearts can develop an arrhythmia, but it is rare. Many things can damage your heart’s electrical system and lead to an electrical problem: diseases of the heart valves, enlargement of the heart, coronary artery disease, high blood pressure, lung disease, congenital heart problems (existing at birth) and scarring from a heart attack.
