Relationships among regional diastolic impairment, elongation of global time to peak filling rate, and global diastolic function using ECG-gated myocardial perfusion SPECT in heart failure

Objective The relationships among regional diastolic impairment, the elongation of global time to peak filling rate (g-TPF), and global diastolic function were examined by a novel program using electrocardiography-gated myocardial perfusion single-photon emission computed tomography (SPECT) (GMPS) in heart failure (HF).
