Fingertip Pulse Wave (PPG signal) Analysis and Heart Rate Detection
To study heart beat pulse wave propagation in real time and to evaluate the vascular blood flow resistance an important physiological parameter for vascular diagnostics. Photoplethysmography is a non-invasive technique that measures relative blood volume changes in the blood vessels close to the skin. PPG analysis emphasizes the importance of early evaluation of the diseases We present the resu...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
15 صفحه اولPulse Rate Analysis from the Photoplethysmographic Signal for Turbulence Detection
In this paper we assessed the possibility of using the pulse rate (PR) extracted from the photoplethysmographic signal for turbulence detection as an alternative to the heart rate (HR). The study is based on analysis of the rhythm changes observed during 4131 ventricular premature beats of 27 subjects. Classical features for turbulence analysis, turbulence onset and turbulence slope were estima...
متن کاملRegular pulse rate but irregular heart rate?
This 30-year-old male patient attended the emergency department because of dizziness accompanied by selfassessed regular pulse rates of 30–40 bpm. Physical examination was normal but cardiac auscultation revealed frequent premature beats. A subsequent 12-lead ECG documented the arrhythmia (Fig. 1). Similar episodes had occurred 12 months ago but thorough cardiac evaluation, including echocardio...

The patterning and morphogenesis of body appendages – such as limbs and fins – is orchestrated by the activities of several developmental pathways.Wnt signalling is essential for the induction of limbs. However, it is unclear whether a canonical Wnt signalling gradient exists and regulates the patterning of epithelium in vertebrate appendages. Using an evolutionarily old appendage – the median ...
