Abstract Some anti‐mycobacterial drugs are known to cause QT interval prolongation, potentially leading to life‐threatening ventricular arrhythmia. However, the highest leprosy and tuberculosis burden occurs in settings where electrocardiographic monitoring is challenging. The feasibility and accuracy of alternative strategies, such as the use of automated measurements or a mobile electrocardiogram (mECG) device, have not been evaluated in this context. As part of the phase II randomized controlled BE‐PEOPLE trial evaluating the safety of bedaquiline‐enhanced post‐exposure prophylaxis (bedaquiline and rifampicin, BE‐PEP, versus rifampicin, SDR‐PEP) for leprosy, all participants had corrected QT intervals (QTc) measured at baseline and on the day after receiving post‐exposure prophylaxis. The accuracy of mECG measurements as well as automated 12L‐ECG measurements was evaluated. In total, 635 mECGs from 323 participants were recorded, of which 616 (97%) were of sufficient quality for QTc measurement. Mean manually read QTc on 12L‐ECG and mECG were 394 ± 19 and 385 ± 18 ms, respectively (p
