Extraction of cardiac signal data

摘要

A T-wave offset point of an ECG signal is provided. In accordance with various example embodiments, a location of a QRS complex in the ECG signal is identified and used to determine a first time window of the ECG signal in which to search for a T-wave offset point. The T-wave offset point is identified within the first time window, and the identified T-wave offset point is provided as an output based upon a noise characteristic of the ECG signal in a second time window that includes at least a portion of the T-wave.

1. An apparatus comprising:
a circuit-based computer configured and arranged with executable instructions to
identify a T-wave offset point within a first time window of an ECG signal, andprovide the identified T-wave offset point as an output based upon a noise characteristic of the ECG signal in a second time window that includes at least a portion of the T-wave of the ECG signal.
