To fix a patient’s irregular heartbeat, doctors first tested its digital ‘twin’

AI Summary

medium article 3 min

Researchers at Johns Hopkins University have developed digital "twins" of patients' hearts to improve treatment for ventricular tachycardia, a dangerous irregular heartbeat. The FDA allowed the technology to guide treatment for 10 patients in a small clinical trial. These custom models, created using advanced MRI scans and other patient data, simulate treatment approaches on the virtual heart to predict how the real organ will react. Doctors can then use this information to better target ablation, the main treatment for the condition, where catheters are used to burn misfiring tissue. The study, published in the New England Journal of Medicine, suggests digital twins could improve care for this condition, which contributes to approximately 300,000 U.S. deaths a year. Larger studies are needed to confirm these findings.
