Asystole, a rare but fatal complication of electroconvulsive therapy (ECT), occurred in 48.7% of patients. Greater heart rate pressure product (RPP) variation after stimulation may provoke asystole in patients with a reactive autonomic nervous system.

Area of Science:

  • Cardiology
  • Neuroscience
  • Psychiatry

Context:

  • Electroconvulsive therapy (ECT) is used to treat psychiatric disorders.
  • Asystole is a rare but potentially fatal complication of ECT.
  • Cardiac activity during ECT electrical stimulation is not well understood.

Purpose:

  • To investigate cardiac movements during electroconvulsive therapy (ECT) electrical stimulation.
  • To determine the incidence of asystole during ECT.
  • To explore the relationship between cardiac autonomic nervous system activity and asystole during ECT.

Summary:

  • Thoracic echocardiography observed cardiac movements in 50 psychiatric patients undergoing ECT under general anesthesia.
  • Asystole (absence of heartbeat >2 seconds) was observed in 57 instances (48.7%), with immediate recovery in all cases.

  • Asystole cases exhibited significantly greater variation in Rate Pressure Product (RPP) post-stimulation compared to non-asystole cases (P=0.0082).

    • Impact:

    • Findings suggest ECT electrical stimulation activates the parasympathetic nervous system, while convulsion activates the sympathetic system.
    • A greater increase in RPP post-stimulation may provoke asystole in patients with a highly reactive autonomic nervous system.
    • This study enhances understanding of ECT-induced cardiac events and autonomic nervous system responses.
