Transmural heterogeneity of Na+-Ca2+ exchange: evidence for differential expression in normal and failing hearts.

abstract：:Five fetal sheep (gestational age, 118 to 125 days) were instrumented to measure impedances of the lower abdominal aorta. Four days after surgery, flow and pressure pulses were recorded during control conditions and during infusion of norepinephrine (0.3 to 3 micrograms.min-1.kg-1 body weight) or angiotensin II (0.2 t...
