Hypocalcemia prolongs the QTc interval. Total calcium (TCa) measurement can be misleading in cases where the concentration of albumin is abnormal. We aimed to investigate which calcium level —ionized calcium (iCa) or TCa—may be more closely related to the QTc interval in COVID-19 patients in whom hypocalcemia and hypoalbuminemia are observed frequently. Adult patients hospitalized for COVID-19 were included in this study. ICa levels were obtained from the venous blood gas sample examined during the emergency department admission, and the TCa levels were obtained from the biochemistry results on admission. The pH-adjusted iCa (Corrected-iCa) and albumin-adjusted TCa (corrected-TCa) were calculated. The QT interval was measured from the admission ECG and corrected for heart rate using the Bazett formula. Hundred and thirty-two patients were included in the study. The mean age was 50±19 years, and 62 (47%) patients were female. Median iCa level was 1,13 mmol/L (1,08-1,18 interquartile range (IQR)), median TCa level was 2.13 mmol/L (2.02-2.22 IQR). 76 patients (57%) had hypocalcemia (iCa |
