This invention is a low cost, reproduceable device designed to reproduce atrial fibrillation (AFib) in swine to create a large animal model of persistent AFib. Using a Raspberry Pi Pico microcontroller to burst pace, this device allows for more modularity and can be programmed with many common programming languages. This large animal model can help researchers understand the mechanism of persistent AFib and develop and test new treatments, medications, ablation, and cell-based therapy. Background: Atrial fibrillation (AFib) is the most common arrhythmia in adults in the US and is growing globally due to an aging population. The current state of care for AFib consumes a lot of time and resources with limited patient success. Currently, there is demand for a device that can persistently reproduce Afib in animal models.
