QT Correction Formulas Compared to The Rule of Thumb ("Half the RR")

Dr. Smith's ECG Blog

The rule of thumb is less accurate, and the risk is higher because a long QT in the presence of bradycardia ("pause dependent" Torsades) predisposes to Torsades. 6) Use a different rule of thumb for bradycardia : Manually approximate both the QT and the RR interval. 3) At heart rates below 60, far more caution is due.
