Autoregressive Modeling of the Photoplethysmogram AC Signal Amplitude Changes after Flow-Mediated Dilation in Healthy and Diabetic Subjects

Mina Amiri; Edmond Zahedi; Fereydoun Behnia

Volume 7, Issue 1 , June 2013, , Pages 85-95

  It is proved that the endothelial (artery inner lumen cells) function is associated with cardiovascular risk factors. Among all the common non-invasive methods employed in the research setting for assessing endothelial function, flow-mediated dilation is the most widely used one. This technique measures ...  Read More

Wireless Heart Beat and Respiratory Rate Monitoring Using a Short-range Wireless System

Zahra sadat Hosseini; Mohadese Arabgari; Ali Farmad; Leili Goldoozian; Hamid Reza Maghari; Sara Aghajari; Edmond Zahedi

Volume 7, Issue 3 , June 2013, , Pages 277-285

  In this article a wireless patient monitoring system for vital signs (respiratory rate and heart beat) is presented. The recorded biosignal is the photoplethysmogram using a probe attached to the patient's finger. This signal is amplified, filtered and digitized by an on-board processor unit before finally ...  Read More

Linear correlation of the fingertip and radial artery photoplethysmograms during normal and deep breath

Adib Keikhosravi; Edmond Zahedi

Volume 6, Issue 4 , June 2012, , Pages 307-317

  The photoplethysmogram (PPG) is a low cost and ubiquitous signal and has always had a great significance in cardiovascular parameter identification such as arterial dilation due to a stimulus. The PPG is generally recorded from the fingertip which is affected by the auto-regulation mechanism (ARM), preventing ...  Read More
