摘要:
The physical properties of the electroconvulsive therapy (ECT) stimulus markedly affect both efficacy and side effects. We review basic principles in characterizing these physical properties and in quantifying the ECT stimulus. The topics discussed include the application of Ohm's law, alternative composite units of ECT dosage (energy and charge), the use of constant-current, constant-voltage, and constant-energy principles in ECT devices, the nature of current shunting in ECT and the determinants of impedance, the relations between impedance and seizure threshold, the seizure-eliciting efficiency of alternative stimulus waveforms and of stimulus parameter configurations, and the role of reactive components (capacitance and inductance) in the ECT circuit. New findings are also presented regarding several of these issues.

摘要:
From the beginnings of convulsive therapy, the need for some way to assess the therapeutic adequacy of individual treatments has been apparent. Recent work suggests that seizure therapeutic adequacy and adverse effects are dependent on the extent to which the stimulus exceeds the seizure threshold (relative stimulus intensity). Applying this information in clinical practice is problematic because of the variable rise in the seizure threshold that takes place over the treatment course. Attributes of the ictal electroencephalogram (EEG) show promise for alleviating this problem by serving as a marker of relative stimulus intensity. Obstacles that need to be overcome in order to implement ictal EEG indices as a relative stimulus intensity marker in clinical practice are discussed and include artifacts, how to determine a threshold for deciding adequacy, variation in technique between sites, and inter-individual EEG variation; some strategies for overcoming these hurdles are described. It is anticipated that an ictal EEG algorithm that addresses these issues is likely to be of substantial clinical benefit in the practice of electroconvulsive therapy.
