QT / QTc Interval Measurement in Irregular Rhythms
2 Approaches:
 • Measure and calculate the QTc for 10 successive beats (using the RR interval immediately before the associated QT interval), and average them.
 • Measure and calculate the QTc for the QT intervals immediately following the longest and shortest RR intervals on the EKG, and average them.
