The effect of a single dialysis session on spatial QRS-T angle in haemodialysis patients.
BACKGROUND Abnormal values of the spatial angle between the directions of ventricular depolarization and repolarization (QRS-T) reflect the action potential inhomogeneities and predict cardiac events and mortality in various patient groups. The study was designed to (i) compare QRS-T in haemodialysis (HD) patients and healthy subjects, (ii) assess the influence of HD on QRS-T and (iii) evaluate...
متن کاملSpatial QRS-T angle in peritoneal dialysis patients: association with carotid artery atherosclerosis, coronary artery calcification and troponin T.
BACKGROUND Abnormal values of the spatial angle between the directions of ventricular depolarization and repolarization (QRS-T) predict potently arrhythmic events and mortality in various patients groups. The study was designed to estimate QRS-T in a group of peritoneal dialysis (PD) patients, and to assess the possible association between QRS-T and coronary artery calcification (CAC), atherosc...
متن کاملThe Spatial QRS-T Angle: Implications in Clinical Practice
The ventricular gradient (VG) as a concept was conceived in the 1930s and its calculation yielded information that was not otherwise obtainable. The VG was not utilized by clinicians at large because it was not easy to understand and its computation time-consuming. The contemporary spatial QRS-T angle is based on the concept of the VG and defined as its mathematical and physiological integral. ...
متن کاملDialysis adequacy of chronic hemodialysis patients in Zanjan-Iran, 2016
Background: Dialysis adequacy is one of the most important factors in determining the survival rate and mortality of dialysis patients. Objectives: The aim of this study was to determine the dialysis adequacy of patients undergoing chronic hemodialysis at dialysis centers located in the province of Zanjan, located in northwest Iran. Methods: This descriptive cross-sectional study was performe...
متن کاملSpatial QRS-T angle predicts cardiac death in a general population.
AIMS The aim of this study was to assess the prognostic importance of the spatial QRS-T angle for fatal and non-fatal cardiac events. METHODS AND RESULTS Electrocardiograms (ECGs) were recorded in 6134 men and women aged 55 years and over from the prospective population-based Rotterdam Study. Spatial QRS-T angles were categorized as normal, borderline or abnormal. Using Cox's proportional haz...
