Relationship between electrolytes and heart rate variability parameters in end-stage renal failure patients before and after hemodialysis [0.03%]
维持性血液透析患者治疗前后的电解质与心率变异性参数的相关性研究
Tsai Lung Wen,Wang Chung-Kwe,Ing Fang Yang et al.
Tsai Lung Wen et al.
Objective: One of the major causes of death in end-stage renal disease (ESRD) patients under maintenance hemodialysis (HD) is ventricular arrhythmias (VA). Heart rate variability (HRV) has been claimed to be related to di...

T Mironova et al.
Objective: The purpose of the study was to present the results of 15-year application in practical cardiology of the method of high-resolution registration and analysis of heart rate variability (HRV) for diagnosis of the...
Time-frequency analysis of QRS complex with wavelet transform in patients with triple-vessel disease [0.03%]
小波变换在三支冠状动脉病变患者QRS复合波的时间-频率分析
Kei Ota,Takeshi Tsutsumi,Keisuke Kawachi et al.
Kei Ota et al.
Objective: Significant Q-wave is sometimes invisible in the patients with triple vessel disease (TVD) even though TVD is a serious coronary heart disease. We offer the preliminary method to analyze the time-frequency prof...

Normal and abnormal circadian profiles of heart autonomic balance, evaluated by time-related common indicator of heart rate variability [0.03%]
基于心率变异性的时间相关共性指标评估心脏自主神经平衡的正常和异常昼夜节律模式
Mikhail Matveev,Rada Prokopova
Mikhail Matveev
Objective: Heart rate variability (HRV) is an universally accepted method for assessing the heart autonomic balance (HAB). At the same time HRV is a highly specific method, but with a low sensitivity to the cardiovascular...
Why do we need supercomputers to understand the electrocardiographic T wave? [0.03%]
为什么需要借助超级计算机来理解心电图T波？
Mark Potse,A-Robert LeBlanc,Alain Vinet
Mark Potse
Objective: Propagation of depolarisation and repolarisation in myocardium results from an interplay of membrane potential, transmembrane current, and intercellular current. This process can be represented mathematically w...
