Atrial coronary hyperemia and ischemia in response to variations in atrial pressure in dogs.

abstract：:Even though congestive heart failure is extremely common, the mechanisms responsible for the clinical manifestations remain a puzzle. The central and autonomic (sympathetic) nervous systems are responsible for a large part of the clinical manifestations. The role of the nervous system in CHF is discussed briefly. It i...
