A System and Method for Real-Time Ventricular Arrhythmia Localization and Catheter Navigation Using Surface ECG

Unmet NeedVentricular arrhythmias (VAs) are common arrhythmias associated with morbidity, mortality, and impaired quality of life. The current treatment for VAs is a catheter ablation procedure. This procedure is considered moderately successful at best and the success rate dramatically increases when the ablation is performed by experienced operators....

An Intraprocedural Automatic Arrhythmia Origin Localization (AAOL) System

Unmet NeedAbnormal cardiac rhythms are often fatal. Specifically, ventricular arrhythmias, caused by abnormal electrical signals in the ventricles, cause 75 to 80% of sudden cardiac deaths every year. To prevent abnormal electrical activity in patients with various idiopathic ventricular tachycardias (IVA), radiofrequency intracardiac catheter ablation...

Personalized Heart Modeling Using Intramyocardial Fat Deposition on Computed Tomography to Predict Ablation Targets

Unmet NeedVentricular tachycardia (VT) is a life-threatening arrhythmia that contributes significantly to the mortality and morbidity of cardiovascular patients. Catheter ablation of VTs can potentially be curative, but recurrence rates remain unacceptably high. Major technological advancements in VT ablation are often highly invasive, time-consuming,...
