WebThe QTc in a given patient may vary somewhat over the course of the day and tends to be slightly longer in young and middle-aged women than in men. The upper limit of a normal QTc is somewhat debatable, but a cutoff of 0.45 second (450 msec) in men and 0.46 second (460 msec) in women was proposed recently in a consensus document. WebNormal limits for ECG parameters during neonatal period (Davignon et al) These reference values are the best available for the neonatal period. The intervals are 98% confidence intervals (the mean is presented in the parenthesis). Values without confidence interval are simply the 98 th percentile (i.e the upper reference limit).
