Patients who need urgent temporary cardiac pacing due to bradycardia, or elective pacing to prevent heart rhythm disturbances during high-risk arrhythmia interventions, such as transcatheter aortic valve implantation (TAVR), alcoholic septal ablations, etc., will be included. After the temporary pacemaker implantation with active fixation electrode in a correct way, the KronoSafe® external pacemaker fixation system will be placed. The correct functioning of the system (R wave detection, lead impedance and right ventricle threshold) will be checked at 24 hours and every other day until the end of cardiac stimulation. During temporary pacing, associated complications are going to be recorded: lead displacement, capture or sensing failure, generator or lead detachment, and cardiac perforation.'}, 'enrollmentInfo':
