Abstract Reverse–Tako–tsubo (r–TTC) is a rare variant of Tako–tsubo syndrome (TTC). TTC characterized by transient and reversible left ventricular systolic dysfunction, for which an emotional or physical stressful trigger can usually be identified. Clinically, it mimics acute myocardial infarction, with elevation cytonecrosis enzymes no obstractive coronary artery stenosis. On imaging, r–TTC hy...

OBJECTIVE To assess whether a normal electrocardiogram can identify good left ventricular function and obviate the need for routine left ventriculography in patients undergoing cardiac catheterization for suspected coronary artery disease. DESIGN A prospective study of patients undergoing cardiac catheterisation. SETTING A regional cardiac centre. PATIENTS The electrocardiograms, coronary...

OBJECTIVE To evaluate and compare the usefulness of cineventriculographies, before and after nitrate use, to technetium-99m sestamibi scintigraphy for the identification of myocardial ischemia. METHODS Twenty-six patients were studied at basal conditions and 5 minutes after intravenous administration of isosorbide mononitrate (0.3 mg/kg), to evaluate the performance and regional wall motion o...

A consecutive series of 56 patients with chest pain but no evidence of previous myocardial infarction was prospectively studied by radionuclide ventriculography to determine the value of global and regional radionuclide indices in detecting coronary artery disease. The results were correlated with the clinical judgment of chest pain, the results of the exercise electrocardiogram, and the right ...

Left ventricular dyssynchrony can be assessed with phase parameters from radionuclide ventriculography (RNVG), including approximate entropy (ApEn). The input values used to calculate ApEn will affect the results significantly, so it is essential optimise for application. However date, no optimisation applied images has been published. In this paper, generated data were simulate patient images,...

The development of contrast ventriculography is outlined and an experience with 40 meglumine iothalamate ventriculograms in 37 patients is described. The details of the procedure, hazards, value, and indications are discussed.
