Heartbeat rhythms are related to a complex dynamical system based on electrical activity of the cardiac cells usually measured by the electrocardiogram (ECG). This paper presents a mathematical model to describe the electrical activity of the heart that consists of three nonlinear ...
There seems to be a relationship between structural abnormalities and abnormal heart rhythms and conduction abnormalities/disturbances. To the best of our knowledge, this is the first follow-up study applying CMR in patients with MD2 and FSHD1. In inherited neuromuscular disorders such as DMD and ...

All participants completed a questionnaire from a physician evaluating their health status and medical consent for training and CPET. Blood pressure was measured following 10 min of rest while seated in a chair. Three tests were performed and the mean result of the latter two was used. The parti...
Patients with an altered circadian blood pressure pattern have been shown to suffer from higher mortality and morbid- ity for vascular events as compared with patients with normal rhythms (7, 33, 34). Attenuation of the nighttime fall in blood pressure has been shown to be associated with an ...
The incidence of myocardial tissue changes such as focal fibrosis and fat infiltration was also higher at follow-up. There seems to be a relationship between structural abnormalities and abnormal heart rhythms and conduction abnormalities/disturbances. To the best of our knowledge, this is the first...
Heart rhythms were monitored via electrocardiograms. The left anterior descending artery (LAD) was ligated by a 6-0 silk suture at 1 mm below the tip of the left atrial appendage. Successful ligation was verified by echocardiography and by a color change of the heart and ST segment elevation....
The use of fuzzy SVM (FSVM) for classifying EEG-based left and right motor imagery with wavelet features obtained in two sub-bands beta and mu rhythms was proposed in Xu, Zhou, Wang, and Huang (2009). The FSVM classifier has been shown as an effective and promising method for identifying...
There have been some attempts to perform data augmentation using mixup in time-series analysis of biosignals, such as electroencephalogram (EEG) and electrocardiogram (ECG)63, generating virtual biosignals from real biosignals of different types64. While in this work, we implement mixup for data ...
