Get your rhythm back.

Serious heart rhythm disorders called arrhythmias, affect the lives of millions of people daily. Unfortunately, most treatments for these conditions are generic and one-size-fits-all, with mixed results.


But there’s hope.


We believe there is a better way to treat serious heart rhythm disorders such as atrial fibrillation and ventricular tachycardia. Using Abbott Electrophysiology’s technology, doctors can identify the sources of arrhythmias that are unique to each person. Now treatment can be tailored to your individual needs.

The most common heart rhythm disorder, atrial fibrillation (AF, or afib) is a serious global public health problem which affects millions of people around the world. If left untreated, AF doubles the risk of heart-related deaths and also increases stroke risk by up to 500%. Unfortunately, although it is such a serious health problem, AF has historically been difficult to treat with an acceptable degree of success.

In response to this unaddressed need, Abbott, Inc. has developed a unique 3D analysis and mapping solution (the Abbott 3D Mapping System), which consists of the RhythmView Workstation and FIRMap diagnostic catheter. The Abbott 3D Mapping System has been designed to enable physicians to view the electrical activity of the heart, thereby supporting the diagnosis and patient-specific treatment planning for a variety of heart arrhythmias including atrial fibrillation, atrial flutter, atrial tachycardia, and ventricular tachycardia.

The Abbott 3D Mapping System received FDA clearance in 2013 and is now in routine use at several leading medical centers throughout the United States.

Repeat Procedures

A cardiac ablation procedure is one of the recommended treatments for patients who suffer with atrial fibrillation or Afib. The procedure is performed when the normal heart function is damaged. Normally, the heart pumps blood to the entire body through normal electrical activity followed by heart muscle contraction. Unfortunately, one of the drawbacks of cardiac ablation is the need to perform the procedure multiple times.1

During episodes of Afib, the electrical activity of the upper heart chambers called atria is impaired. This abnormal heart function leads to symptoms and increases the risk of stroke. Cardiac ablation procedures are conducted in order to restore the normal conduction of the electrical activity of the atria and heart function. The goal of performing the procedure is that patients experience symptomatic relief as well as minimize their chance of stroke.1

The most common ablation technique consists of isolating the areas in the atria where abnormal electrical activity is diagnosed. Most often, abnormal electrical activity originates in the pulmonary veins or PVs. PVs are vessels that conduct blood into the left atrium from the lungs and are connected to the left atrial walls. When abnormal electrical activity occurs in the PVs, it happens in the left atrium too. The need to isolate the PVs from the rest of the left atrial wall is essential in maintaining normal atrial function.

Despite the fact that the ablation technique has progressed over the past 15 years, up to 40% of cases require a redo. Repeat ablation procedures are targeted at re-isolating the pulmonary veins. Some patients require up to 3 procedures until complete isolation is achieved.1

Many physicians and researchers now conclude that isolating PVs is not the only mechanism that may prevent Afib. The concept that rotational activity or rotors may sustain Afib has caught the attention of major institutions, physicians and even patients. While the focus has been on isolating PVs in the left atrium, rotors appear to have a role in sustaining Afib in the right atrium as well. Initial studies identified that almost 30% of the rotors can be located in the right atrium. During repeat ablation (redo cases), many physicians now combine rotor elimination with re-isolation of the PVs.2,3 This provides physicians with a completely new perspective on how and where to treat Afib during a cardiac ablation procedure.
