A member asked:
Does alcohol prolong the qtc? if so how much necessary or just one drink? borderline long qt, 474.
A doctor has provided 1 answer
QT: Alcohol does not prolong the QT interval but long term alcohol abuse may lead to hypokalemia and hypomagneseia which could cause prolongation. I wonder if your QT interval was corrected for the heart rate and was read by machine or by human.
