WebMay 14, 2022 · Normal QTc values. QTc is prolonged if > 440ms in men or > 460ms in women; QTc > 500 is associated with an increased risk of torsades de pointes; QTc is abnormally short if < 350ms; A useful rule of thumb is that a normal QT is less than half the preceding RR interval

WebDefinitions of normal QTc vary from being equal to or less than 0.40 s (≤ 400 ms), 0.41 s (≤ 410 ms), 0.42 s (≤ 420 ms) or 0.44 s (≤ 440 ms). For risk of sudden cardiac death, "borderline QTc" in males is 431–450 ms; and, in females, 451–470 ms. An "abnormal" QTc in males is a QTc above 450 ms; and, in females, above 470 ms.
