Abstract

The heart failure patient has the varying degree generally between the ventricle or the ventricle does not synchronise the movement, the heart synchronises the treatment (CRT) to be valued people′s more and more again. Echocardiogram each kind of new technology in the heart synchronises in the treatment to have the important function again particularly. This article introduced in detail organises Doppler, the two-dimensional strain, the three dimensional entire volume and the velocity vector image formation and so on supersonic new technology after the appraisal heart synchronism, the CRT patient screens, the instruction actuator place, optimises wrestles the procedure, the appraisal curative effect as well as the technique makes a follow-up visit aspect and so on observation progress and the application.
