Figure 2 Shortening of QT interval (QTc) is more frequent in secondarily generalized tonic-clonic seizures (SGTCS) and predominantly occurs in the early postictal phase

(A) QT values corrected with Fridericia formula at different time points. Number of pairs from left to right: 25, 10, 17, 18, 18. p Values: 0.97, 1.0, 0.0011, 0.001, 0.23. (B) Number of seizures with normal QTc (white) and short QTc (green) in complex partial seizures and SGTCS. Twenty pairs with respective available QTc data were included. (C) Number of observations with short QTc at the time of occurrence (pi: postictal). For all panels: asterisks indicate significance.
