Highly sensitive sensors have been successfully used to map the electrical activity of the developing heart in embryos, in a University of Sussex study published on 10th November, which could lead to new insight into how heart rhythm abnormalities develop, the researchers say.
The team fine-tuned patented Electric Potential Sensing (EPS) technology, developed at the University, to detect the electrical signals of zebrafish embryos from just three days after fertilization. The findings have been published in the scientific journalApplied Physics Letters.
An example of the electrocardiogram mapped from the embryonic zebrafish heart three days after fertilization
This is the first time that scientists have been able to see the full picture of the electrical activity in the developing heart of such a small organism, given that currently electrocardiography (ECGs) methods only measure the heartbeat.
Zebrafish hearts are remarkably similar to those of humans, making them a good model organism…
Yaser Khalifa is a man with many years of experience as an electrical and computer engineer. After graduating from Alexandria University in Alexandria, Egypt, Yaser continued his education by pursuing his PhD in Electrical Engineering at Cardiff University. Upon graduation he leapt into the working world and has since worked with teams made up of people ranging from engineers working on super conductors to fellow professors at SUNY New Paltz. Yaser also has had over 40 papers published in a variety of educational publications. He has worked with such companies as General Electric as an electrical engineer consultant with their global research division as well as numerous others in different capacities. When not working you can find Yaser engaging in his other passions. He is an avid outdoors man and loves to mountain bike whenever possible. He both leads mountain biking tours as well as engages simply for pleasure. He was introduced to the sport by a friend at SUNY New Paltz and has since then volunteered as a biking guide with Minnewaska State Park, among others.
