We have designed and fabricated a low power IC to perform the Inverse 88 DCT transform according to the CCITT precision specifications , suitable for portable video communication devices. Several design techniques have been used to reduce the power, such as a fast algorithm, an architecture that can exploit input signal correlation , and large amount of(More)
Dobutamine stress echocardiography is an established diagnostic method for the detection of myocardial viability in patients with severe left ventricular dysfunction([1]). The presence of viable myocardium identifies patients who will benefit from coronary revascularization, by improving both functional capacity and long-term survival. Occasionally,(More)
OBJECTIVE To quantify regional left ventricular (LV) function and contractile reserve in Q wave and non-Q wave regions in patients with previous myocardial infarction. DESIGN An observational study. SETTING Tertiary care centre. PATIENTS 81 patients with previous myocardial infarction and depressed LV function. INTERVENTIONS All patients underwent(More)
AIMS Aim of the study was to assess the role of early inducible ischaemia for determining left ventricular remodelling in patients with acute myocardial infarction. METHODS AND RESULTS In 179 consecutive patients with first myocardial infarction the occurrence of new wall motion abnormalities during dobutamine stress echocardiography at discharge was(More)
