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.

FDA clears ECG feature for ‘prescription-only’ smartwatch

Another smartwatch has received FDA clearance for an electrocardiogram (ECG) feature. But this one—the Study Watch from Alphabet’s health division, Verily—is a “prescription-only device” rather than a product marketed to all consumers.

USPSTF: Insufficient evidence to support AFib screening with ECG

The U.S. Preventive Task Force (USPSTF) issued a Grade I recommendation, indicating there is insufficient evidence assessing the benefits and harms of screening for atrial fibrillation (AFib) with electrocardiography (ECG) in patients 65 and older with previously undiagnosed AFib.

ECG left ventricular hypertrophy: A good omen before TAVR?

Patients without electrocardiographic (ECG) evidence of left ventricular hypertrophy were significantly more likely to die in the two years after transcatheter aortic valve replacement (TAVR), researchers reported July 30 in Clinical Cardiology.

New Late-Breaking Study Finds Wearable Electrocardiogram (ECG) Monitoring Patch Can Detect Atrial Fibrillation Earlier and More Efficiently than Routine Care

ORLANDO, Fla., March 10, 2018 — The Janssen Pharmaceutical Companies of Johnson & Johnson today announced late-breaking results of a new home-based clinical trial showing that a wearable continuous electrocardiogram (ECG) monitoring patch can identify people with asymptomatic atrial fibrillation (AFib) earlier and more efficiently than routine care.

What does radiology have to do with climate change?

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
