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.

Ventricular Tachycardia

The ventricles are the two lower chambers of the heart, which fill with blood from the two top chambers or the atria. They then pump the blood to the lungs and to the body. Ventricular tachycardia is faster than a normal heart rate (greater than 100 beats per minute) that begins in these lower chambers of the heart.

Ventricular tachycardia occurs when something goes wrong with the electrical signals that control heart rate. This abnormal electrical activity in the heart muscle can be caused by other heart problems including coronary artery disease, high blood pressure, and heart valve disease. It can develop after a heart attack or heart surgery, or can occasionally even occur in people who have no heart disease at all.

The most common symptoms of ventricular tachycardia are:

  • Dizziness
  • Lightheadedness
  • Palpitations
  • Shortness of breath
  • Chest pain

And if the heart rate is elevated too long, more serious symptoms can occur such as fainting and cardiac arrest.

In addition to the presence of symptoms, ventricular tachycardia is diagnosed non-invasively using a device called an electrocardiogram or ECG/EKG for short. Another diagnostic tool is an invasive electrophysiology test to precisely evaluate the electrical activity in different regions of the heart.

Treatment of ventricular tachycardia may include medications, a radiofrequency catheter ablation and/or an implantable cardioverter defibrillator (ICD). In a radiofrequency catheter ablation procedure, the physician identifies the origin of the abnormal electrical activity and then uses a device called an ablation catheter to deliver radiofrequency energy to that area. The result is usually the destruction of the tissue responsible for the abnormal heart rate.

An ICD is a device that is implanted under the patient’s skin, which monitors the heart’s rate/rhythm. If the ICD detects an abnormal heartbeat, it sends an electrical signal to the heart to restore normal rate/rhythm.
