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.

AliveCor receives first FDA clearance to detect a serious heart condition in an ECG on a mobile device

AliveCor, Inc. announced today that the U.S. Food and Drug Administration (FDA) has granted the company clearance for its algorithm to detect atrial fibrillation (AFib), the most common form of cardiac arrhythmia.

30-day ECG monitoring spots candidates for anticoagulation

Prolonged electrocardiographic (ECG) monitoring in patients with cryptogenic stroke improved the detection of atrial fibrillation by a factor of five compared with standard 24-hour monitoring, results published June 26 in the New England Journal of Medicine showed. Detection changed anticoagulation treatment as well.

Cloud-based platform may make ECG data easier to assess

A new Web-based platform that analyzes multimodal signals may help make electrophysiological data easier to evaluate and incorporate into clinical research, according to a study published in the March issue of the Journal of the American Medical Informatics Association.

ECGs as part of athlete screenings less favored in U.S.

Although a majority of medical experts recently polled believe young athletes should be screened for cardiac disease before participating in sports, less than half of providers in the U.S. say electrocardiograms (ECGs) should be included, according to an article published March 6 in the New England Journal of Medicine. The majority of their European counterparts, on the other hand, do favor ECGs as part of the process.

Shopping for an ECG? Good luck

Hospitals appear to be more than willing to share price information with healthcare consumers, if the item of interest is a parking spot. But divulging costs on items such as an electrocardiogram (ECG) is another thing.

Magnetic ECG may detect lethal cardiac rhythm in utero

Magnetocardiography accurately diagnosed long QT syndrome (LQTS) in fetuses, according to a study published online Nov. 12 in Circulation.

App outperforms email for sending ECG images

An experimental cellphone app that transferred echocardiogram (ECG) images from emergency personnel to hospitals proved to be faster and more reliable than emailing images, according to an oral abstract presented May 17 at the American Heart Association’s Quality of Care and Outcomes Research scientific sessions in Baltimore.

ECG results in AF patients predict adverse outcomes

Results from routine electrocardiograms (ECGs) in patients with atrial fibrillation (AF) can accurately predict later adverse events, researchers reported Oct. 28 at the Canadian Cardiovascular Congress in Toronto.
