Relationship between QT dispersion and a heart failure survival score

We assessed the relationship between QT dispersion and a heart failure survival score (HFSS). 12-lead ECGs were recorded to computer during 18 cardiac transplant assessment sessions on 17 patients. The HFSS was calculated for each subject from clinical data. QT intervals were measured manually and by an automatic technique. HFSS ranged from 6.27 to 9.80, with five assessments classified as low-risk (HFSS/spl ges/8.1), seven classified as medium-risk (7.2
