Why are EKG and QTc questions central?
Ibogaine is discussed in the literature because it can affect cardiac electrical activity, including QT interval prolongation. The medical overview of long QT syndrome describes why prolonged cardiac repolarization can matter: it may be associated with dangerous rhythm disturbances. An EKG is one part of a broader evaluation; the QTc is a corrected measurement that requires qualified interpretation in context.
Ask what cardiac history is reviewed, when an EKG is obtained, who interprets it, how QTc considerations are handled, and what findings would lead to postponement or referral. A clinic should be able to explain its process plainly without promising that any screening removes risk.
