Abstract
Noninvasive techniques such as echocardiography, nuclear magnetic resonance imaging and nuclear medicine studies (radionuclide ventriculography and myocardial perfusion scintigraphy with single photon emission tomography), provide indirect information about ventricular synchronism when parameters of mechanical contractility are used. The Fourier phase analysis is a useful tool for the use of nuclear techniques for this purpose, and has been applied in both radionuclide ventriculography and perfusion scintigraphy. A review in time of the basics and clinical applications of nuclear techniques in the study of ventricular synchronism is presented in this article. Nowadays, the gated-SPECT scintigraphy is the most common among nuclear techniques because it allows assessing perfusion, function, and intraventricular synchronism in the same test.
