Official Title: Right Ventricular Hypertrophy and Pulmonary Hypertension: A Correlation Analysis Between Tc-99m Tetrofosmin SPECT Adn Echocardiography
Brief Summary: The study hypothesis is that a quantitative index can be derived from Tc-99m myocardial perfusion scans that accurately identifies the presence of left ventricular hypertrophy and pulmonary hypertension. Echocardiography provides the reference standard.
