The measurements of s-Ca and other electrolytes were made on the blood sample taken on the same day of the electrocardiogram (ECG) recordings. The normal range of s-Ca and three QTc intervals was determined in 50 outpatients with no cardiac disease. Three QT intervals in the hypercalcemic ...

57 found that for individual subjects the QTc varied over 24 hours of ambulatory monitoring by an average of 76 ms (range 35 to 108 ms).57 Molnar et al.58 reported that during ambulatory monitoring the upper limit for the mean QTc interval was 439 ms in normal men and 452 ms in ...

The control values of the QT intervals (mean value 433 ms, range of the mean values 422453 ms), were comparable. After thiopental, the mean values in the groups were no longer in the normal range (<440 ms). After atropine, the values at 3 min were statistically significantly prolonged ...

On a normal ECG, you’ve got the P, Q, R, S, and T waves. The QT interval spans from the start of the Q to the end of the T wave. Long QT syndrome, or LQTS, is when somebody’s QT interval is longer than normal, which should typically be less than half of a cardiac cycle...
