ABSTRACT:
A system, apparatus and method for determining prognosis in atrial fibrillation non-invasively detects electrical activity of the heart with external electrodes, such as with ECG leads. The diagnostic system, apparatus and method provide a non-invasive technique to classify the severity of atrial fibrillation according to peak frequency of the fibrillation, and provide useful information for treatment of the atrial fibrillation, including the prediction of conversion with ibutilide, and the estimation of time to recurrence after cardioversion.
