How long before your doctor finds out about this and sets up protocols to use it post stroke? I'm guessing never.
New Technology Improves Atrial Fibrillation Detection After Stroke
Researchers
have developed a new method of evaluating electrocardiographic signals
that outperforms current approaches used to detect atrial fibrillation
after stroke, according to a study published in Stroke.
The technology, called electrocardiomatrix, examines large amounts of telemetry data by converting 2-dimensional signals from an electrocardiogram (ECG) into a 3-dimensional heatmap that allows for rapid inspection of all collected heartbeats.
“We validated the use of our technology in a clinical setting, finding the electrocardiomatrix was an accurate method to determine whether a stroke survivor had [atrial fibrillation],” said Jimo Borjigin, PhD, University of Michigan Medical School, Ann Arbor, Michigan.
For the study, Dr. Brown and colleagues collected telemetry data from 265 patients with ischemic stroke and transient ischemic attack between April 2017 and January 2018 for examination facilitated by electrocardiomatrix. The researchers compared the electrocardiomatrix results with the clinical team’s medical record documentation of atrial fibrillation identified through telemetry.
The study found that the electrocardiomatrix identification method was successfully applied in 98% of cases. The positive predictive value of electrocardiomatrix compared with clinical documentation was 86% overall and 100% among a subset of patients with no prior history of atrial fibrillation.
“We originally noted 5 false positives and 5 false negatives in the study,” said Dr. Borjigin. “[However,] expert review actually found the electrocardiomatrix was correct instead of the clinical documentation we were comparing it [with].”
Additionally, the researchers recently demonstrated the usefulness of the electrocardiomatrix to differentiate between atrial fibrillation and atrial flutter, and it has also shown an ability to capture reduced heart rate variability in patients with life-threatening injuries and illnesses.
Dr. Borjigin envisions electrocardiomatrix technology will soon be used to assist the detection of all cardiac arrhythmias online or offline and side-by-side with the use of ECG.
“I believe that sooner or later, electrocardiomatrix will be used in clinical practice to benefit patients,” she concluded.
