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. - Dr. Eric Strong @DrEricStrong - Strong Medicine https://www.youtube.com/c/EricsMedi #QT #QTc #Interval #Measurement #Irregular #Rhythm #cardiology #diagnosis #ecg #ekg #electrocardiogram
