New ultrasound technique could sharpen heart arrhythmia diagnosis

This study tests a new, non-invasive ultrasound method called electromechanical wave imaging (EWI) to see if it can more accurately locate and diagnose heart rhythm problems compared to standard tests. About 322 adults already scheduled for a heart procedure will get an EWI scan beforehand. Half of them will have their EWI results shared with their doctor to help plan the procedure. The goal is to see if EWI improves diagnosis and makes treatments more efficient.
