Novel Notch Detection Algorithm for Detection of Dicrotic Notch in PPG Signals
Photoplethysmography (PPG) is a non-invasive optical technique that measures relative blood volume changes in the blood vessels and is widely used for research and physiological studies. Dicrotic notch represent the closure of the aortic semi-lunar valve and subsequent receding blood flow when ventricles relax. Their location is used to calculate systolic time intervals and monitor cardiac func...
متن کاملFPGA Based Digital System for Detection of Dicrotic Notch in the Carotid Pulse Signal
Heart disease is one of the leading causes of death in human beings. A survey shows every year about 900,000 peoples die due to heart diseases worldwide. Carotid pulse is a pressure signal recorded over the carotid artery as it passes near the surface of the body at the neck. An abnormal carotid pulse called the dicrotic pulse occurs when patients suffer from sepsis, hypovolemic shock, cardiac ...

امروزه استفاده از منابع انرژی پراکنده کاربرد وسیعی یافته است . اگر چه این منابع بسیاری از مشکلات شبکه را حل می کنند اما زیاد شدن آنها مسائل فراوانی برای سیستم قدرت به همراه دارد . استفاده از میکروشبکه راه حلی است که علاوه بر استفاده از مزایای منابع انرژی پراکنده برخی از مشکلات ایجاد شده توسط آنها را نیز منتفی می کند . همچنین میکروشبکه ها کیفیت برق و قابلیت اطمینان تامین انرژی مشترکان را افزایش ...
15 صفحه اولThe dicrotic notch analyzed by a numerical model
Divergent concepts on the origin of the dicrotic notch are widespread in medical literature and education. Since most medical textbooks explain the origin of the dicrotic notch as caused by the aortic valve closure itself, this is commonly transmitted in medical physiology courses. We present clinical data and numerical simulations to demonstrate that reflected pressure waves could participate ...

Short-lived red blood cells (RBCs) might save you from malaria, but the iron that they dump out could kill you in other ways, say Roy et al. (page 2949). The extra iron seems to feed the bug that causes typhoid fever. Typhoid fever, which is caused by Salmonella, can be cured easily in most patients with simple antibiotics. But infected individuals who also suffer from sickle cell anemia or β-t...
