Ibogaine is associated with cardiac arrhythmia risk, including QTc prolongation. The QT interval represents part of the heart’s electrical recovery cycle; the corrected QT, or QTc, accounts for heart rate. A prolonged QTc matters because it can be associated with dangerous rhythm disturbances, including torsades de pointes.
That risk is not abstract. It is why a preparation process should account for a baseline ECG, clinical review of personal cardiac history, current medications and substances, and factors that may alter electrolytes or heart rhythm. The wider preparation checklist for ibogaine treatment is most useful when it makes room for this level of scrutiny before any treatment setting is considered.
QTc is central because it offers a measurable signal of electrical risk—but a number alone cannot replace a setting that can recognize deterioration and act immediately.
