    This study details a novel electroconvulsive therapy (ECT) device offering precise voltage and current control for safe alternating current (ac) signal delivery. The machine enables detailed characterization of patient impedances during unilateral ECT procedures.

    Area of Science:

    • Biomedical Engineering
    • Neuroscience
    • Medical Devices

    Background:

    • Electroconvulsive therapy (ECT) requires precise electrical parameter control for safety and efficacy.
    • Existing ECT devices may lack sophisticated control over voltage, current, and signal duration.
    • Understanding patient impedance is crucial for optimizing ECT delivery.

    Purpose of the Study:

    • To describe the design of a novel, servo-controlled electroconvulsive therapy (ECT) machine.
    • To ensure safe and controlled delivery of alternating current (ac) signals during ECT.
    • To facilitate detailed characterization of patient impedances during unilateral ECT.

    Main Methods:

    • Design of an isolated output, servo-controlled voltage ECT machine.
    • Implementation of 60-Hz ac signal delivery with adjustable voltage (0–230 V rms) and duration (0.1–2 sec).

  • Inclusion of current limiting (360–770 mA rms) to accommodate varying patient impedances (50–500 Ω).

    • Main Results:

    • The designed ECT machine provides safe, controlled application of electrical stimuli.
    • The device allows for precise regulation of voltage, current, and stimulus duration.
    • The equipment facilitated the detailed measurement of impedances characteristic of unilateral ECT.

    Conclusions:

    • The developed ECT device enhances safety and control in electrical stimulus delivery.
    • This technology enables precise characterization of electrophysiological parameters during ECT.
    • The findings contribute to a better understanding of patient impedance in unilateral ECT.
