<qa>  What is the goal of this study?The aim of this study is to determine if in the early phase of diagnostic assessment cardiogoniometry can improve differentiation between patients with cardiac ischemic emergency and patients with non-cardiac non-ischemic cause of pain. Furthermore it will be evaluated if cardiogoniometry is capable to diagnose patients with non-ST-elevation myocardial infarction NSTEMI to the same extent as Troponin. This could avoid time loss until a possibly necessary catheter intervention fast track.
