Nanotechnology has been broadly defined as the one for not only the creation of functional materials and devices as well as systems through control of matter at the scale of 1-100 nm, but also the exploitation of novel properties and phenomena at the same scale. Growing needs in the point-of-care (POC) that is an increasing market for improving patient's quality of life, are driving the development...
Alternans is characterized by changes of interbeat intervals (IBI) and blood pressure amplitudes (BPA) on a beat-to-beat basis. We hypothesize that an impaired myocardial performance influences the duration and amplitude of the alternans and could enhance the diagnostics in patients with dilated cardiomyopathy (DCM). ECG and non-invasive blood pressure were recorded from 91 DCM patients and 45 healthy...
Baroreflex sensitivity (BRS) and heart rate variability (HRV) have significant influence on the patients' prognosis after cardiovascular events. The following study was performed to assess differences in the response of the autonomic regulation in hypertensive and normotensive patients undergoing cardiac surgery with heart-lung machine. 166 consecutive patients were enrolled in a prospective study;...
