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.

Long-term Follow-Up of Afib Patients: A Single-center Experience

Long-term Follow-up of FIRM-guided Ablation of Atrial Fibrillation: A Single-center Experience 1

Patent Characteristics:

This is a large 80 patient study with 2 years of follow-up. The majority of patients had persistent AF (75% persistent, with 18% being long-standing persistent) and other high-risk co-morbidities such as sleep apnea and heart failure.

Study Findings:

The location and distribution of rotors identified and long-term results were consistent with those identified with previously published results of FIRM-guided ablation.234
A large percentage of LA rotors were identified outside the PVs and the posterior wall.
A much lower incidence of focal sources were identified (~4%) which is consistent with the results reported in the Multicenter Registry.3
RA rotors were identified in a high percentage of patients, thereby reinforcing the importance of the right atrium in the treatment of atrial fibrillation.
Finally, the results indicate that the elimination of rotors is an effective endpoint.
