Which condition should prompt notifying the provider before electroconvulsive therapy?

• A. Cardiac arrhythmia
• B. Asthma
• C. Crohn's disease
• D. Renal colic

Answer: (A)

Cardiac arrhythmia should prompt notifying the provider before electroconvulsive therapy because ECT causes rapid autonomic changes that affect the heart. At seizure onset there can be a brief parasympathetic (vagal) surge causing bradycardia, followed by a strong sympathetic surge leading to tachycardia and hypertension. In someone with an existing arrhythmia, these shifts can trigger dangerous rhythm disturbances or unstable blood pressure. Alerting the provider allows for medical clearance, tailored anesthesia plan, and appropriate cardiovascular monitoring to manage any rhythm problems during treatment.

Asthma, Crohn's disease, and renal colic don’t pose the same direct, acute risk to heart rhythm during ECT, though they may necessitate general considerations for anesthesia or overall health.
