Effects of amiloride in guinea-pig and rat left atrial contraction as affected by frequency of stimulation and [Ca2+]0-[Na+]0 ratio: role of Na+/Ca2+ exchange.

1. The effect of amiloride (0.5 mM) on guinea-pig and rat left atria driven at various rates of stimulation and different [Ca2+]0-[Na+]0 ratios has been studied. 2. Amiloride elicited a positive inotropic response in guinea-pig left atria driven at 0.1 Hz, 0.5 Hz and 1 Hz when [Ca2+]0 was 3.6 mM, 1....
