The typical ECG pattern of hypocalcemia consists of QT prolongation due to ST segment prolongation.The QTc rarely exceeds 140% of normal. If hte QT exceeds that number, the U wave is likely to be included in the measurement. The T wave is usually of normal width but can be narrow based ...
Daytime mean HR gave a mean value of 93 ± 10 (range 71148), while during night hours it was 74 ± 11 (range 5498). The minimum QT interval averaged 261 ± 10 ms for HR> 120 and the maximum 389 ± 9 ms for HR ¤ 60; the corresponding mean value of QTc (i.e., QT corrected...
