Electrocardiography

Electrocardiograms (ECG) are a primary cardiac diagnostic test that measures the electrical activity in heart to identify overall cardiac function, arrhythmias and areas of ischemia and infarct. Standard 12-lead ECG breaks the 3D structure of the heart into 12 zones, each showing the electrical activity in that specific area of the heart. This narrows down areas where there are issues with coronary artery disease or electrophysiology issues. Many ambulatory heart monitors and consumer-grade ECG monitors use fewer leads so are less specific as to cardiac conditions or location of abnormal heart rhythms, but can show an issue that requires further diagnostic testing or treatment.

A majority of medical devices involved in Class I recalls were never required by the U.S. Food and Drug Administration (FDA) to undergo premarket or postmarket clinical testing, according to new research published in Annals of Internal Medicine.[1]

AI-powered ECG screening a cost-effective way to ID heart failure patients

The technique was especially cost-effective in outpatient settings, according to a new study of more than 22,000 patients.

Researchers have found that homemade play-putty can effectively capture electrocardiogram (ECG) signals at a level comparable to commercially available electrodes. The play-putty is made with a simple mix of flour, water, salt, cream of tartar and vegetable oil—but the potential is much more than one may expect.

Homemade electrodes made of putty capture heart data as well as some commercial devices

The putty, made with basic ingredients found around the house, can effectively capture ECG measurements.
