Cardiac mapping on ex vivo perfused porcine slaughterhouse hearts: A Langendorff perfusion protocol for epicardial mapping on isolated beating hearts

Cardiac mapping techniques, in which an electrode-array is placed directly on the surface of the heart, were developed to gain a better insight in the underlying electropathology of cardiac arrhythmias. This procedure is performed in patients undergoing cardiac surgery, but here not all relevant cardiac structures and conduction inquiries can be...
