Photoplethysmography (PPG) is a non-invasive detection method that detects blood volume changes in living tissue by recording video through a network camera, using an active appearance model to determine facial landmarks and head [5,6]. Extracting biometric information from face video images, pre-...
Compounding this problem is the poor signal-to-noise ratio (SNR) of the PPG signal in some subjects, which can be caused by either their darker skin or poor perfusion of arterial blood. Certainly, motion artifacts will cause a poor SNR, hence, any algorithm that is able to discriminate ...
Consuming heavy amounts ofalcoholfrequently can lead to a fast and irregular heart rate (atrial fibrillation). This again is a medical emergency. A persistent high heart rate can also mean that the heart muscle is weakened, which forces it to pump harder to deliver the same amount of blood....
Yes. However, one of the techniques used is called grounding. Grounding has been shown to dramatically improve blood flow. So if you are on blood thinning tablets, you must consult your doctor about coming off them while you perform the grounding protocol. These exercises can cause powerful cle...
Then please pay attention. Cardiac arrhythmias are not (always) harmless. The irregular pumping of the heart causes blood clots in the heart’s chambers. These blood clots can end up in your bloodstream and cut off the blood flow when they get stuck in your blood vessels. As a result the...
The variables for the GRACE 2.0 (age, heart rate, blood pressure, creatinine, Killip class, cardiorespiratory arrest on admission, elevated cardiac enzymes, ST segment elevation) and TIMI (age > 65 years, cardiovascular risk factors, coronary stenosis > 50%, two episodes of Angina in...
↑ Blood volume →↑ ventricular filling Initially, these adaptations can increase cardiac output and prevent the development of symptoms (compensated HF). However, it can also result in: ↑ Afterload ↑ Preload Over time, hypertrophy decreases lumen size and fails to increase contractility →...

![CDATA[The objective of the present study was to evaluate the use of audible chart-recorded doppler ultrasonography (DUS) to monitor both uterine blood flow and fetal heart rate (FHR) during pregnancy in dairy cattle. Possible applications of DUS include the monitoring of fetal distress when a...
The blood samples were stored at – 80 °C. An electrochemiluminescence immunoassay (ECLIA) was used to detect levels of NT-ProBNP as part of routine clinical care (Roche Diagnostics, Mannheim, Germany). ImP in serum was measured at BEVITAL (bevital.no) using a targeted metabolomics approach...
