I. INTRODUCTION
QT-prolongation can cause the development of life threatening ventricular tachyarrhytmias such as Torsade de Pointes (TdP) and ventricular fibrillation often leading to cardiac death. QT-prolongation and TdP has been identified as a side effect of many commonly used medications [1]. Thus QT-analysis plays a major role for pharmaceutical industry on their way to developing new drugs.
