RESUMO

In cases of chronic congestive heart failure, QT-interval dispersion is a strong predictor of death. Carvedilol therapy appears to decrease QT-interval dispersion. We investigated whether carvedilol reduces QT-interval dispersion in congestive heart failure and whether this pharmaceutical agent has additional effects on elderly patients.
