Abstract Electroanatomical mapping systems are being utilized clinically for locating arrhythmias within a given patient’s heart. Today, employed endocardial invasive and require extensive set-up time. Epicardial systems, like CardioInsight™ from Medtronic, non-invasive but co-registration of electrodes to the heart, e.g. via required Computed Tomography (CT) scan. This system has been used both in several laboratories situ. The difficulties with vitro uses that ex vivo perfused hearts lack an associated thoracic cavity, resulting possibility inconsistent placement electrodes, poor conduction epicardial signals. We developing our laboratory means use on reanimated large mammalian hearts. Preliminary studies were conducted swine hearts, this could be also human making research even more translatable. will allow critical observations during pacing or ablation experiments collecting data computational modeling.
