Microheterogeneity of subsarcolemmal sodium gradients. Electron probe microanalysis in guinea-pig ventricular myocytes.

1. The effect of stimulation on possible subsarcolemmal sodium accumulation was studied in ventricular myocytes (2 mM [Ca2+]o, 36 degrees C). By trains of eighteen paired voltage-clamp pulses (180 ms to 0 mV, 20 ms to -45 mV, 180 ms to +50 mV, 620 ms to -45 mV) unloaded contractions were potentiated...
