Asystole during electroconvulsive therapy (ECT) is rare but serious. This study identifies unique risk factors for asystole occurring after ECT seizures in healthy men, distinct from poststimulus risks.

Area of Science:

  • Cardiology
  • Neurology
  • Anesthesiology

Background:

  • Asystole is a rare but life-threatening complication of electroconvulsive therapy (ECT).
  • Existing research has focused on risks for asystole immediately following ECT stimulation.
  • Risks for asystole occurring at other times during ECT have not been well-defined.

Observation:

  • Two cases of asystole occurring postictally (after seizure) during ECT in healthy adult males were analyzed.
  • Common features among these cases were identified to understand the specific risk factors.

Findings:

  • Shared risk factors for postictal asystole differed from those for poststimulus asystole.
  • Common factors included adult (not geriatric) age, male sex, good overall and cardiac health, mesomorphic build, anticholinergic premedication, vigorous ECT seizure, and low resting heart rate.

  • Both patients had a history of postictal bradyarrhythmia during previous ECT sessions.

    • Implications:

    • Postictal asystole shares similarities with postexertional asystole observed in athletes.
    • Consideration of higher doses of atropinic and sympatholytic agents, alongside vigilant postictal cardiac rhythm monitoring, is recommended for at-risk patients, particularly those with prior postictal bradyarrhythmia.
