Abstract

ATRIAL FIBRILLATION (AF) is the most common cardiac arrhythmia. In the United States alone, it affects more than 2.5 million people annually. The onset of AF is frequently associated with thoracic surgery and it is estimated to occur in 25% of patients that undergo cardiac surgery. The AF may be preceded by changes in electrocardiogram (ECG) characteristics such as premature atrial activity, heart rate variability (HRV), and P-wave morphology [3]. A valid question regarding the availability of a time lag that could be used to provide adequate treatment against AF onset was raised by Dr. Lombardi in his editorial [1]. We are using a hybrid neuro-fuzzy prediction model that exploits non-linear interactions between ECG parameters. The techniques are non-invasive and analyze 5-lead ECG waveforms. This will allow the model to be easily applied in a Cardio-Vascular Intensive Care Unit setting with very few modifications.
