 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.
