Q: Even though my doctor told me I am pretty healthy, she ordered an electrocardiogram (ECG) to be done right in her office. Besides a heart attack, what else can ECGs show? A: Cardiac (heart) cells ...

An EKG can detect disruptions in the heart’s electrical activity, potentially indicating damage from a past heart attack, but it is most accurate when used with other tests. While an EKG can help ...

Engineers at the University of California San Diego have developed a powerful new tool that monitors the electrical activity inside heart cells, using tiny "pop-up" sensors that poke into cells ...

Researchers at the University of Toronto's Institute of Biomedical Engineering have developed a new method to mature ...

Scientists today track electrical signals and voltage changes in neurons and muscle cells by labeling individual cells or probing with electrodes. Scientists have now developed a new type of sensor ...

Sept. 25 (UPI) --Researchers have succeeded in creating a digital twin that for the first time replicates the heart's electrical conduction system, which coordinates heartbeats, a new study says. The ...

Complete heart block means that there’s a complete separation of electrical activity between the upper and lower chambers of the heart. Without prompt medical attention, it can be fatal. Your heart ...

It is still elusive to what extent interactions between different cell types of the heart influence the normal heart rhythm and possibly trigger life-threatening arrhythmias. A new measurement method ...

When Allister McGuire was working on his doctorate at Stanford University, he bought a lot of fertilized chicken eggs from Trader Joe’s. McGuire doesn’t study chickens; he’s a chemist, and he was ...
