<p>A method and apparatus for the non-invasive, dynamic tracking and diagnosing of cardiac vulnerability to ventricular fibrillation features simultaneous analysis of T-wave alternans (206) and heart rate variability (204). T-wave alternation is an absolute predictor of cardiac electrical instability. Heart rate variability is a measure of autonomic influence, a major factor in triggering cardiac arrythmias. By simultaneously analyzing both phenomena (208) the extent and cause of cardiac vulnerability can be assessed.</p> |
