Beta-adrenergic drive mediates faster LV relaxation during tamponade in dogs; leaves open relevance to human tamponade.
Does acute cardiac tamponade accelerate left ventricular relaxation in conscious dogs, and is this dependent on beta-adrenergic influence?
Acute cardiac tamponade accelerates left ventricular relaxation in conscious dogs, a response that is dependent on intact beta-adrenergic signaling rather than changes in loading conditions.
Nishikawa et al. (1994) studied this question.
