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.

E-cigarettes linked to AFib, other heart rhythm issues in ‘highly concerning’ new study

“The findings of this study are important because they provide fresh evidence that the use of e-cigarettes could interfere with normal heart rhythms—something we did not know before,” according to one specialist.

Vaccine-related myocarditis was seen in approximately 0.00005% of children between the ages of 12 and 15. All cases were mild, and the median length of stay at the hospital was three days.

“Our ultimate goal is to prevent strokes," one Mayo Clinic electrophysiologist said. "I believe the current study has brought us one step closer.”

The U.S. Food and Drug Administration (FDA) has granted the first pediatric indication for use for an implantable cardiac monitor to Medtronic. The Linq II Insertable Cardiac Monitor (ICM) system is the first such device receive 510(k) clearance for use in pediatric patients over the age of 2 who have heart rhythm abnormalities and require long-term, continuous monitoring.
