"If hERG 1a/1b heteromers represent a significant fraction of channels contributing to I Kr, down-regulation of 1b would enhance sensitivity to hERG blockers up to four-fold and increase the risk for arrhythmia by having a predominant population of more drug sensitive hERG 1a channels rather than the relatively less sensitive hERG 1a/1b channels."
