1. A method of assessing a patient'"'"'s cardiac vulnerability to sudden cardiac death using an electrocardiogram signal, the method comprising:
- defining a relationship between depolarization and repolarization;
determining a first value representative of the relationship for a first beat of the electrocardiogram signal;
determining a second value representative of the relationship for a second beat of the electrocardiogram signal; and
analyzing variation between the first value and the second value to assess the patient'"'"'s cardiac vulnerability to sudden cardiac death.

Abstract
Method and apparatus for assessing a patient'"'"'s cardiac vulnerability to sudden cardiac death. The method can include defining a relationship between depolarization and repolarization, determining a first value representative of the relationship for a first beat, determining a second value representative of the relationship for a second beat, and analyzing variation of the first value and the second value to assess the patient'"'"'s cardiac vulnerability to sudden cardiac death.
