In the first scenario, the simulation resulted in a ventricular pause of 1333ms (Boston Scientific), 2000ms (Medtronic and Microport), and 2340ms (Biotronik). In the second and third scenario, different results were observed across devices. All simulations of the second and third scenario resulted in repetitive 21 block response (during eight cycles) in Boston Scientific and Biotronik devices. These scenarios were confirmed in patient cases. Simulator based observations of unanticipated pacemaker-induced 21 block response during exerc
