Researchers at Columbia Engineering School in the US have developed a new electromechanical wave-imaging method, the first non-invasive, direct technique to map the electrical activation in the heart and diagnose arrhythmias.
Results from a study reported that the EWI technique allowed researchers to imaged the heart with ultrasound five times faster than standard echocardiography and was able to map local deformations.
Electromechanical wave imaging is based on ultrasound imaging.
Elisa Konofagou, an associate professor at the Columbia University Fu Foundation School of Engineering and Applied Science, said that since ultrasound is safe and low cost, the future could see physicians can carrying portable ultrasound scanners to map the activation of the heart during a routine visit.
