A patient is diagnosed with ischemia (i.e., lack of blood flow) in a left lobar pulmonary vein. The attending physician determines that the ischemia is due to a vasospastic episode. Constriction of this left lobar pulmonary vein is controlled by ____________. A. B. C. D. E. Efferent fibers from the phrenic nerve. Post-ganglionic fibers from T1-T4 sympathetic trunks Post-ganglionic fibers from the vagus n.

Pericardiocentesis is needed to drain fluid from the pericardial cavity to relieve pressure on the heart.
