The European Society of Cardiology and the International Olympic Committee recommend including electrocardiography (ECG); this test records the electrical impulses in the heart and provides information about abnormal heart rhythms and other heart conditions....
According to previous studies, blood flux oscillations can be separated into different components in the frequency domain35,36,37,38, which might reflect different physiological rhythms39. However, from a complexity perspective point of view, these components are indivisible and are part of a multisc...
The second heart sound is heard during which phase of the cardiac cycle? Identify the pathophysiology of cardiac disorders. The pathopysiology of cardiac disorders would depend on the disorder, right? What is atrial fibrillation associated with? What are the ...
Three 5-min ECG signal samples were selected: one each from the N2 and N3 stages of non-rapid eye movement (NREM) sleep and one from the rapid eye movement (REM) stage of sleep. All samples were taken from the second NREM–REM ultradian cycle. Samples were selected for the absence of...

It was detected using wave-by-wave analysis of cardiorespiratory rhythms and was considered to reflect a strategy of anxiety management involving the activation of a neural pacemaker. Results were consistent with slow breathing, but contained uncertainty at normal breathing rates (0.2–0.4 Hz). ...
