Heart rate variability according to electrolyte changes during hemodialysis in patients with chronic kidney disease

Abstract Funding Acknowledgements Type of funding sources: None. Background Autonomic neuropathy commonly arises as a long-term complication in chronic kidney disease (CKD) and can be diagnosed from heart rate variability (HRV), calculated electrocardiogram (ECG) recordings. Purpose There is limited data about HRV using real-time ECG according to electrolyte levels during hemodialysis (HD) patients with CKD. Methods Total 50 (62.1±10.7 years) CKD underwent continuous monitor (237.4±15.3 mins) HD for remote monitoring system checked before/after HD. And we compared levels. Results During the monitor, total 2374 times level simultaneously all patients. Both time frequency domain were higher when had lower K+ change (<0.5mEq/L) those (>0.5mEq/L) Table. In addition, there incidence arrhythmic events including atrial/ventricular premature complexes, even though no difference mean group (P<0.001). Conclusions Poor controlled was independently associated This further substantiated by independent associations between measures HRV. These strongly suggest that cardiac autonomic dysfunction caused alone.
