the mechanisms that control release of ca2+ from the sarcoplasmic reticulum ( sr ) of guinea-pig ventricular cells were studied by observing intracellular calcium concentration ( [ ca2+ ] i transients ) and membrane currents in voltage-clamped guinea-pig ventricular myocytes perfused internally with fura-2 .
