QT interval variability during exposure to acute hypoxia

Petra Zupet, ┼Żarko Finderle, Todd T. Schlegel & Vito Starc
Objective: Ventricular repolarization instability as quantified by the index of QT interval variability (QTVI) is one of the best predictors for risk of malignant ventricular arrhythmias and sudden cardiac death. Because it is difficult to appropriately monitor early signs of organ dysfunction at high[for full text, please go to the a.m. URL]
