ABSTRACT:
A medical device and method for predicting life-threatening cardiac arrhythmias (LTCA) by gathering electrocardiographic data such as intervals between heart beats (RR-series) or other signal, mathematically decomposing or compressing the signal into several elements or components that contain the most significant information and tracking the changes in the several elements. The signal may be divided into time windows, and the signals decomposed into a plurality of coefficients or components such as Karhunen Loeve Transformation (KLT) coefficients that are predictive of the occurrence of LTCA. The electrocardiographic data may be generated real-time, on-line, or be prerecorded data.
