Latest Patents

Lundstrom's latest patents include an "Electrocardiogram signal processing apparatus" and a "Method and apparatus for correcting non-physiological variations in ECG." The first patent describes a computerized apparatus designed to process multi-lead ECG beat signals. It features an averager unit that provides a template ventricular beat signal and a subtraction unit that generates a residual signal by subtracting the template from the multi-lead ECG beat signal. An alignment stage enhances the relative alignment of the two signals, ensuring more accurate results.

The second patent outlines a method for correcting non-physiological variations in ECG signals. This involves conditioning and digitizing signals recorded during a heartbeat. The signals are stored in a matrix format, and the differences between the measuring matrix and a reference matrix are minimized through various operations, including translation and time synchronization.
