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.

Abnormal ECGs common in NBA players; more research required to pinpoint athletes at risk

Even with criteria modified for athletes, National Basketball Association (NBA) players are more likely than other athlete groups to have abnormal electrocardiographic (ECG) findings, according to a report in JAMA Cardiology.

Low-risk patients opt for annual ECGs—despite clinical recommendations

Despite many physicians’ reticence to recommend annual electrocardiograms as part of a yearly physical, a study conducted in Canada proved that more than one in five annual health exams lead to one.

Individual feedback key to reducing excessive ECGs

An educational intervention designed to reduce ordering of transthoracic echocardiograms (TTEs) informs physicians about their own test-ordering patterns and how their performance compares to their peers, according to recent research. Such knowledge can reduce inappropriate use of the tests.

ECG reveals clinical findings obscured by left ventricular hypertrophy

A man born with a congenital heart murmur developed systemic arterial hypertension as an adult. At age 50, he went to the hospital because of dyspnea. He also had a pulmonic valve ejection click and murmur of pulmonic stenosis. When at the hospital, his echocardiogram showed hypertrophy of both ventricles as well as an enlarged right atrium.

Around the web

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

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."
