An arrhythmia is often controlled with medication. However, if diagnostic tests determine you need a procedure to correct your irregular heartbeat, you'll get the care you need at Lehigh Valley Health Network’s Chrin Heart and Vascular Center. Our arrhythmia specialists perform more than 1,500 procedures every year. We are the second hospital in Pennsylvania to perform balloon cryoablation, a procedure that corrects atrial fibrillation, the most common type of irregular heartbeat.
We provide these arrhythmia treatments:
During an ablation procedure, a thin, flexible tube (catheter) is inserted into a blood vessel through a small incision. Using X-ray technology, a physician guides the catheter to the area of the heart that contains the tissue causing the irregular heartbeat. With the catheter in place, two different procedures can be performed to destroy the faulty tissue. Your doctor will determine which of these procedures is best for you:
- Radiofrequency ablation – An electrode at the end of the catheter creates heat which is used to cauterize and destroy the tissue.
- Balloon cryoablation – A balloon at the tip of the catheter is filled with liquid nitrous oxide which is used to freeze and destroy the tissue. We were the first hospital in the area and second in Pennsylvania to perform this procedure.

Cardiac resynchronization therapy involves a minor surgical procedure during which a biventricular pacemaker is implanted under the skin, usually in the shoulder area. It synchronizes your heart’s two lower chambers so they contract at the same time. In clinical trials, patients with this implant had dramatically improved heart function, and quality of life.
During cardioversion, small paddles are used to deliver a small electrical shock to the heart through the chest wall. The shock restores your heart’s normal rhythm. Your heart and blood pressure are closely monitored during cardioversion.
The Convergent procedure uses extreme heat (radiofrequency) to produce scar tissue (lesions) on the heart to block abnormal electrical signals. During the procedure, a cardiothoracic surgeon and heart rhythm specialist (electrophysiologist) work as a team in a single setting. The surgeon creates lesions on the outside surface of a beating heart through a small incision in the abdomen. The electrophysiologist then threads a thin, flexible tube (catheter) through a vein in the groin to reach the heart and fills in any gaps in the lesion pattern. Diagnostic techniques confirm all abnormal electrical signals have been interrupted. This procedure is successful in 75-80 percent of patients with difficult-to-treat atrial fibrillation.
During FIRM ablation, the flow of electricity within the heart is analyzed while the patient is in atrial fibrillation. This is achieved using a basket catheter, which is placed inside the heart to record the heart’s abnormal rhythm. Electrodes on the basket catheter locate areas of the heart – called anchor points or rotors – where the electrical signal stops moving forward and instead spins in a circle. A heart rhythm specialist (electrophysiologist) then uses extreme heat to produce scar tissue on the rotors and force the heart’s electrical signals to proceed in an orderly manner. FIRM ablation has an 80 percent success rate and helps people stay symptom-free for up to two years.
Learn how Lehigh Valley Health Network can use a subcutaneous implantable defibrillator (S-ICD) to monitor your heart’s electrical activity and regulate your heartbeat. Electrophysiologist Hari Joshi, MD, describes the procedure, for which patients it’s appropriate, and its benefits and risks.
An implantable cardioverter defibrillator is a small electronic device that continuously monitors the electrical activity of the heart. It can deliver varying levels of electrical impulses based on the severity of your irregular heartbeat. It is about the size of a stopwatch and usually is inserted under the skin in the upper chest. The ICD also can function as a basic pacemaker as needed. Generally, when an irregular heart rhythm is detected, the mildest electrical impulse is delivered first. If the normal heart rhythm is not restored, additional stronger impulses will be delivered. Your doctor will program your ICD to your specific needs.
The maze procedure involves making a series of surgical incisions in the heart’s upper chambers. These incisions then heal into scars that force the heart’s electrical signals to proceed in an orderly manner, restoring normal heart rhythm. The procedure has a high success rate, but because it requires open-heart surgery, it usually is reserved for people who do not respond to other arrhythmia treatments such as medications.
During a minimize procedure, flexible instruments are inserted through incisions between the ribs. The instruments deliver radiofrequency energy to create scars in the upper chambers of the heart. These scars force the heart’s electrical signals to proceed in an orderly manner, restoring normal heart rhythm.
A pacemaker is a small device implanted under the skin, usually in the shoulder area, that sends electrical signals to start or regulate a slow heartbeat. A pacemaker may be implanted if the heart's natural pacemaker (the SA node) is not functioning properly and has developed an abnormally slow heart rate or rhythm, or if the heart’s electrical pathways are blocked.
