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 address 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 solutions (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 band is now in routine use at several leading medical centers throughout the United States.

FIRMap® Catheter

Medical stethoscope and technology concept.In addition to the RhythmView® Workstation, a novel panoramic contact-mapping catheter has been designed with complex arrhythmias and the associated heart anatomy in mind.

The FIRMap Catheter is used to capture electrical potentials from the endocardium, which can be used in conjunction with the RhythmView Workstation to create activation maps to aid in the diagnosis of cardiac arrhythmias.

The basket design conforms to the shape of the heart chamber, enabling the ability to create maps from hard-to-reach areas such as near the distal and proximal ends of the basket. Previous generations of basket catheters are often blind to these areas.

The FIRMap Catheter has a total of 64 evenly spaced electrodes, distributed between 8 splines (8 electrodes per spline). The robust spline design facilitates an even deployment of electrodes across the chamber and reduces spline bunching, which can occur with other basket catheters. Radiopaque marker bands on the splines assist in the positioning of the catheter and aid in the localization of sources identified by the RhythmView Workstation. A broad range of catheter sizes can accommodate a wide variety of patient anatomy.


Designed to work within the heart’s anatomy, the FIRMap (Focal Impulse and Rotor Modulation) panoramic contact-mapping tool optimizes the clinician’s view of full-chamber, continuous electrical activity. This unique diagnostic catheter is sized to the patient’s chamber, mapping the anatomy from a stable position. Data from the FIRMap catheter is sent to the RhythmView mapping system for processing.

FIRMap features include:

  • A basket design that conforms to the shape of the heart chamber
  • The ability to create maps from hard-to-reach areas such as locations near the distal and proximal ends of the basket
  • Sixty-four evenly spaced electrodes, distributed between 8 splines
  • A broad range of sizes to accommodate a wide variety of anatomy
