Abstract:
The relation between dynamic mid-ventricular obstruction provoked by dobutamine infusion and chest pain was investigated in 16 patients with normal echocardiograms at rest who had histories of unexplained chest pain. Chest pain was induced in 63% of dynamic mid-ventricular obstruction and beta blockers suppressed either dynamic mid-ventricular obstruction or Chest pain.
