From: Evaluation of Tp-e interval, Tp-e/QT ratio and Tp-e/QTc ratio in patients with acute myocarditis

  Arrhythmia Patients (n = 4) No Arrhythmia Patients (n = 52) p
Heart rate (bpm) 101 ± 36 89 ± 17 0.27
QT interval (ms) 355 ± 41.2 371 ± 49.7 0.52
QTc interval (ms) 453 ± 91.1 436 ± 53.1 0.55
QRS interval (ms) 100 ± 28.2 119 ± 21.2 0.08
