Abstract:
The extracellular fluid space in rabbit SA node and atrial trabeculae was measured with 14C-inulin and 14C-sucrose. A larger 14C-inulin space in SA node than in the atrial tissue, indicated a greater extracellular fluid space in the former, and could be due to caveolae on the pacemaker cell membrane.
