QT Intervals
The QT interval is measured from the onset of the QRS to the end of the T
Between HRs of 70-100, the T wave should be over by half of the R-R interval
Corrected QT (QTc): measured QT divided by the square root of R-R interval (in seconds)
Male: normal QTc <0.44s
Female: normal QTc <0.46s
Prolonged QT
Short QT
