qtd

This inter-lead difference was called QT interval dispersion (QTD) and was defined as QT maximum minus QT minimum measured from 12 leads.

Objective: To observe the reduction of QT dispersion(QTd) in patients with acute myocardial infarction(AMI) treated with urokinase.

Objective: To analyze the change between heart rate and QT dispersion (QTd) in acute stage patients with cerebral apoplexy.

The Qtd function is a shortcut function for the PeriodsToDate (MDX) function whose level expression argument is set to Quarter.

Conclusion: There is significant change in heart rate and QTd in acute stage patients with cerebral apoplexy.

Objective To introduce a method of computer automatic measurement of QTd.

In the recovery period of AMI, l ow fasting blood glucose is another independent factor of QTd increase.
