title: The residual myocardial contractile reserve in the rational use of digitalis.
abstract: A simple noninvasive method for the estimation of residual myocardial contractile reserve by using the postextrasystolic stimulation and systolic time intervals is proposed. The rational use of digitalis, avoiding the toxic effects, is possible only if the presence or absence of the residual contractile reserve is taken into consideration.
