Effect of self-correlation on the relation between QT interval and cardiac cycle length.

abstract：BACKGROUND:Systemic markers of inflammation increase after percutaneous coronary intervention (PCI). The rise in inflammatory markers after PCI is frequently attributed to the inflammatory stimulus associated with coronary artery injury during balloon inflation and coronary stent implantation. The aim of this study was...
