Acute effects of cardiac resynchronization therapy on left ventricular Doppler indices in patients with congestive heart failure.

abstract：:In a double-blind, randomized crossover study of 12 patients suffering from chronic bronchitis, the comparative influence of equipotent doses of pindolol (5 mg) and metoprolol (100 mg) on the bronchodilatory potential of inhaled fenoterol (0.4 mg), a beta 2-agonist, was investigated by means of body plethysmography.
