Changes of Heart Rate Variability After Coronary Bypass Grafting

Background: Heart rate variability (HRV) may serve as a follow‐up parameter in patients with coronary artery disease undergoing percutaneous transluminal angioplasty. Several studies have shown significant changes of HRV parameters in the case of restenosis. The value of this method as a prognostic parameter in patients following coronary artery bypass grafting (CABG) is unknown.
