Key result
Increased T-wave residuum (P=0.022) and PCA ratio (P=0.005) were significant predictors of cardiovascular mortality beyond QTc and clinical risk factors in American Indians.
Why the study?
Do novel descriptors of T-wave complexity provide additional prognostic information beyond QTc and PCA ratio for predicting all-cause and cardiovascular mortality in American Indians?

p-value: p=<0.001
Novel ECG descriptors of T-wave complexity, particularly T-wave residuum, provide incremental prognostic value beyond standard clinical variables, QTc, and PCA ratio for predicting mortality.
No takes yet. Share an insight, caveat, or question.
T-wave residuum may refine CV mortality prediction beyond QTc in American Indians; extends ECG markers but leaves open prospective validation.
Okin et al. (2005) reported a cohort. ECG repolarization abnormalities (QTc, PCA ratio, T-wave residuum) vs. Normal repolarization was evaluated on All-cause and cardiovascular mortality (p=<0.001). Increased T-wave residuum (P=0.022) and PCA ratio (P=0.005) were significant predictors of cardiovascular mortality beyond QTc and clinical risk factors in American Indians.
