We propose the method to compute the nonlinear parameters of heart rhythm (correlation dimension D₂ and correlation entropy K₂) using 5-minute ECG recordings preferred for screening of population. Conversion of RR intervals' time series into continuous function x(t) allows getting the new time series with different sampling rate dt. It has been shown that(More)
Lagged Poincaré plots have been successful in characterizing abnormal cardiac function. However, the current research practices do not favour any specific lag of Poincaré plots, thus complicating the comparison of results of different researchers in their analysis of heart rate of healthy subjects and patients. We researched the informative nature of lagged(More)
There is a strong evidence in medical education literature that the learner-centred curriculum favouring the use of metacognition and self-learning is very proficient. However, ethnocultural and verbal environment may undermine learners' ability to utilise the learning strategies, leading to inefficient learning. This study aimed to investigate the personal(More)
