    The study included 287 patients under 30 years old with mental disorders undergoing modified electroconvulsive therapy (MECT).

  • 2

    Key factors influencing initial seizure duration during MECT were age, energy percentage, and etomidate dose, contributing over 79% of explanatory power.

  • 3

    The random forest classification model achieved an average precision of 76.9%, recall of 75.1%, and F1-score of 74.4% in predicting seizure duration.

  • 4

    Disease type, antiepileptic drug usage, and gender had minimal impact on seizure duration compared to age, energy percentage, and etomidate dose.

  • 5

    The study recommends setting the initial energy percentage to 1/3–2/5 of the patient's age to optimize seizure duration during MECT.
