Ultrasound’s arrhythmia localization surpassed ECG’s accuracy

Key clinical point: Electromechanical wave imaging is a new way to localize the source of a cardiac arrhythmia.

Major finding: Electromechanical wave imaging localized the arrhythmia origin correctly in 96% of patients versus 71% for ECG.

Study details: A single-center, blinded, prospective study with 55 patient.

Disclosures: The study received no commercial support. Dr. Wan had no disclosures. Columbia University holds patents related to electromechanical wave imaging.
