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.

About Us

Topera® (now Abbott Electrophysiology) began as the inspired story of one doctor’s unwavering commitment to improve the life of one of his arrhythmia patients. As a dedicated researcher at University of California, San Diego and a practicing cardiac electrophysiologist at the San Diego VA Medical Center, Dr. Sanjiv Narayan had a deep appreciation for heart rhythm disorders and their profound effect on the everyday lives of people.

When a patient, who had undergone three failed procedures to correct his atrial fibrillation (Afib), sought his advice, Dr. Narayan believed the solution was to first identify, then target the mechanism that was sustaining the patient’s Afib. Catheter ablation risks can increase in patients who undergo the procedure multiple times.

Using his own prototype version of the Focal Impulse and Rotor Modulation (FIRM) mapping software, Dr. Narayan, with the help of his colleague Dr. Ruchir Sehra, was able to identify a rotor in an area not usually targeted for treatment. A rotor is a rotational wave that drives surrounding disorganized activation and fibrillation. Once the rotor was eliminated via cardiac ablation, the patient enjoyed long-term freedom from Afib. This breakthrough led to the development and validation of a novel diagnostic system to help identify the sources that sustain Afib and the eventual formation of Topera.

Topera was founded on a single, focused mission that still guides every aspect of the business today: To become the recognized global leader in identifying the sources of arrhythmias which enables patient-specific solutions.

Abbott acquired Topera in 2014 and created a new electrophysiology division committed to improving the diagnosis and treatment of Afib. Now called Abbott Electrophysiology or Abbott EP, this commitment to offer Afib and other arrhythmia patients more options will continue to expand worldwide. Abbott EP intends to solve one of the most critical and unmet needs in cardiac ablation: better patient outcomes. For the first time, physicians can identify patient-specific sources that sustain serious heart rhythm disorders using the Topera Physiologic Rotor Mapping Solution.
