Relationship With Calcium, Nutrition Risk, QTc Interval, Tp-e Interval, and Tp-e/QTc Ratio of Critical Care Patients.

QTc interval, Tp-e interval, and Tp-e/QTc ratios are significantly increased in patients with high nutrition risk score compared with healthy people and are independently associated with calcium and serum albumin levels; thus, they can be used more effectively in the follow-up of cardiac fatal arrhythmias.
