Display of cardiac activation pathways with echocardiography

摘要

Abstract: The study of cardiac activation dynamics is an important factor in the characterization of the cardiac function. One such example is the localization of WPW-pathways inside the myocardium. Accurate localization of these pathways can be used to determine if the patient should be treated with catheter techniques or surgical techniques. This paper analyzes the temporal information in tissue velocity imaging with both qualitative and quantitative methods. The clinical experiments indicate that echocardiography can become an alternative technique for non-invasive electrophysiology in these kinds of applications. !5
