A 61‑year‑old man developed massive QT prolongation after ingesting a very large ibogaine dose (65–70 mg/kg), progressing to ventricular flutter at 270 bpm and near‑fatal cardiac arrest requiring defibrillation. This represents the highest survived ibogaine dose reported, with the QT interval taking seven days to normalise due to the drug’s long half‑life.
