HEALTH - HEART - 3 Biomarkers found EKGs of patients who later died from cardiac-related issues had similar aberrant patterns

the scientists found that those patients with one of the abnormalities, as noted by the biomarkers, were two to three times more likely to die within the year.

The scientists analyzed the EKGs from more than 4,500 heart attack patients. And they found that the EKGs of patients who later died from cardiac-related issues had similar aberrant patterns.

3 biomarkers to be found EKG data. 1. so-called "morphologic variability" which is the amount of change in the shape of normal heartbeats over a long period of time. 2 is "heart rate motifs" which are sequences of changes in heart rate that show whether and how the heart is responding to the body’s nervous system. 3 is "symbolic mismatch" which compares how similar a patient’s EKG is to another patient with a similar medical history.
