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.

Atrial Tachycardia

Atrial tachycardia (AT) is a type of rapid heart rhythm abnormality that originates from a discrete focal area of the atria, or upper chambers of the heart. This disorder is sometimes called focal atrial tachycardia.

Symptoms of Atrial Tachycardia

Typical symptoms of atrial tachycardia are often similar to atrial flutter and atrial fibrillation. These include sudden palpitations, dizziness, trouble breathing, and syncope or passing out. Unlike AT, atrial flutter is not a small focal area of the heart but rather a large abnormal circuit often encompassing the whole atrium. Atrial fibrillation can have focal areas that sustain the rhythm but these are typically multiple and the rhythm pattern is irregular.

Causes and Treatment

AT can have numerous causes:

  • Reversible AT due transient abnormalities in the body
  • Congenital AT
  • AT due to aging or other heart disease
  • AT as a consequence of prior heart procedures such as surgery or cardiac ablation

Reversible AT can be due to temporary abnormalities such as very abnormal body electrolytes from dehydration. It’s easily treated by targeting the abnormality.  Patients with congenital AT are born with it, often presenting in childhood or early adulthood. It can be controlled with medications or effectively with catheter ablation procedures.

AT can also be a consequence of aging or other heart disease causing progressive disease in the heart’s electrical system. This may lead to certain focal areas to have rapid electric beats. Management of this type of AT depends on a patient’s underlying health and typically consists of drugs to regulate the rhythm and/or catheter ablation.

One of the most common causes of AT today is a prior heart procedure. Children born with congenital heart disease that requires heart surgery often develop AT decades later in the regions of the heart where surgery was performed. With the growth of catheter ablation, AT has been noted to be a common arrhythmia in patients with symptoms that reoccur. These focal ATs are often located near previous ablation scars. Treatment of these post-procedural focal ATs is more difficult that other ATs and require either drugs or further procedures.
