Hcq causes a prolongation off the QT interval putting one at risk for arrhythmias but does not cause ischemia

In an interview w/Dr Z, hosted by Dr Drew Pinsky, they both agreed that the QT prolongation, in the HCQ trials, were in (IIRC) less than 1% of patients...and, (IIRC) these particular patients had underlying conditions (AIDS being one).
