title: ECT stimulus dose dependence on current separately from charge.
abstract: Bilateral electroconvulsive therapy (ECT) seizure threshold charge averaged 162.8 and 125.1 mC at 900 and 1150 mA, respectively (p<0.02), measured in randomized balanced order (N=18). Results are consistent with stimulus dose strongly depending on current besides charge, rather than charge alone. ECT stimuli of differing currents but equal charge differ in dose.
