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.

Researchers launch study to evaluate risks, benefits of ECG screening in high school athletes

Researchers in Texas are launching a pilot study examining whether electrocardiograms (ECGs) are useful in identifying high school athletes who are at risk of sudden cardiac death.

Researchers develop ECG risk equation to predict cardiovascular disease mortality

Researchers have developed a risk score based on demographics and automated electrocardiography (ECG) data that performs comparably to the Framingham risk score and the pooled cohort equation when assessing possible cardiovascular disease mortality.

CCTA races past treadmill ECG for cost, performance

Coronary CT angiography (CCTA) saves time and money compared with exercise treadmill tests for assessing low- to intermediate-risk patients who present with chest pain. In a randomized trial, CCTA also performed better diagnostically.

AliveCor launches new app to auto detect atrial fibrillation in an ECG recording

AliveCor, Inc. announced today the launch of the latest version of the AliveECG app, which provides patients with free real-time atrial fibrillation (AF) detection in ECG recordings using its new FDA-cleared algorithm. The new app helps patients and physicians manage existing conditions with intelligent, personalized and easy-to-use new features.
