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.

First large-scale studies of wearable ambulatory cardiac monitoring shed light on usage 

Matthew Reynolds, MD, Lahey Hospital and Medical Center, explains data from the EXCALIBER and CAMELOT studies that show ambulatory cardiac monitoring usage among more than 300,000 patients.

Using ECG AI to find the cardiac amyloidosis needles in the haystack

Early detection of cardiac amyloidosis is leads to the best outcomes, but it is often missed until later stages. AI is being developed to help detect these patients earlier using ECG and echo.

The U.S. Food and Drug Administration (FDA) announced that Vyaire Medical has recalled the twin tube samples lines from its Vyntus CPX Metabolic Cart due to ongoing safety concerns. This is a Class I recall, which means the FDA believes using these devices “may cause serious injuries or death.”

If left unchecked, the devices could put patients at risk of serious injuries or death as they undergo cardiopulmonary evaluations.
