- standard deviation of normal-to-normal QT interval (SDNN (QT))
- root-mean-square of the successive QT interval difference (rMSSD (QT)),
- QT interval variability index (QTVI).

Summary
Brief summary
It is hypothesized that renal transplant recipients with renal graft dysfunction are prone to cardiac arrhythmia's and sudden death secondary to changes in cardiac structure and function.
