The reliability of electrocardiographic detection of serum ionized Ca level was studied in 13
preterm and 32 full term infants.
The concentration of ionized Ca was measured with a new ion-selected electrode, NOVA SP4
(NOVA Biomedical, Waltham, MA USA).
The Q-oTc interval correlated with total Ca (r=o.553, p<0.01) and ionized Ca (r= -0.435, p<
0.01) but the Q-Tc interval did not correlate with total and... |
