20080249425 | Method and Apparatus for Defining Cardiac Time Intervals - A method and apparatus for defining cardiac time intervals using the pre-systolic diastolic filling period and the proceeding systolic period. The diastolic period can begin at the end of the T wave and terminate at the onset of the proceeding Q wave as defined in electrocardiograph signals. The systolic period can begin at onset of the Q peak and terminate at the end of the T wave as defined in electrocardiograph signals. | 10-09-2008 |
