Abstract
Conclusion
QT dispersion, measured from a routine 12-lead ECG following acute myocardial infarction complicated by heart failure provides independent information regarding the probability of long-term survival. However, the low sensitivity of this electrocardiographic marker limits its usefulness for risk stratification if used in isolation.
Key Words: QT dispersion, myocardial infarction, heart failure
