downstream chamber—namely, the left atrium. Such a pressure measurement is termed the pulmonary artery wedge pressure or pulmonary capillary wedge pressure (PCW) and closely matches the left atrial pressure in most individuals. Furthermore, while the mitral valve is open during diastole, the pulmonary venous bed, left atrium, and left ventricle normally share the same pressures. Thus, the PCW can be used to estimate the left ventricular diastolic pressure, a measurement of ventricular preload
high-grade stenosis within the proximal left anterior descending coronary artery. A. Miniaturized reproduction of the complete scan showing tomographic images in each of the three views. The first, third, and fifth rows demonstrate images during stress, and the second, fourth, and sixth rows are matching images acquired at rest. B,C. Enlarged selected panels from A showing stress and rest images in the short axis and horizontal long axis views. The arrows indicate regions of decreased perfusion
99mTc) is bound to red blood cells or to human serum albumin and then injected as a bolus. Nuclear images are obtained at fixed time intervals as the labeled material passes through the heart and great vessels. Multiple images are displayed sequentially to produce a dynamic picture of blood flow. Calculations, such as determination of the ejection fraction, are based on the difference between radioactive counts present in the ventricle at end diastole and at end systole. Therefore, measurements
The dissection continues to the level of the renal arteries (white arrowhead) and beyond. D. In this CTA left posterior oblique view, the dissection extends to the infrarenal aorta (white arrowhead) and involves the left common and external iliac arteries (colored arrowhead). AA, ascending aorta; LCI, left common iliac artery; LEI, left external iliac artery; LK, left kidney; PA, main pulmonary artery; RCI, right common iliac artery; RK, right kidney.

that the mean electrical vector points straight downward (in the direction of arrow c), perpendicular to the lead I axis. Also note the configuration of the inscribed QRS complex in lead I. There is a downward deflection, followed by an upward deflection of equal magnitude (when the upward and downward deflections of a QRS are of equal magnitude, it is termed an isoelectric complex). Thus, when an ECG limb lead inscribes an isoelectric QRS complex, it indicates that the mean electrical axis of
