Abstract
A device for electrostimulation of body tissue through a stimulation electrode, in which a stimulation outcome is detected, at least after delivery of a stimulation pulse, on the basis of detecting a drop in a voltage over time or a rise in a short-circuit current over time at a capacitance including at least one Hemholtz capacitance produced on the surface of the stimulation electrode in conjunction with surrounding body fluid or the body tissue, and wherein the drop in voltage or the rise in short-circuit current is representative of a characteristic drop in a myocardium impedance of the body tissue.
