Does dobutamine potentiate the peripheral chemoreflex in patients with congestive heart failure?
Dobutamine increases ventilation during normoxia, but not during hyperoxia in patients with CHF. We conclude that dobutamine enhances peripheral chemoreflex sensitivity in patients with congestive heart failure.
Planimetry of aortic valve area by TOE is difficult and less accurate than the continuity equation for assessing the severity of aortic stenosis.
