QT prolongation increases the risk of torsades de pointes
and sudden cardiac death, although the evidence base to suggest
this is exponential is limited; there are exceptions in that some drugs
prolong the QT interval but do not increase dispersion of repolarisation.
However, more robust data indicate that, once the QTc interval
is >500 ms, the risk of torsades de pointes in significantly increased.
exponential，原意是指数,幂。这个地方不知道应该怎样理解？
